Arin’s Real Name and Early Life

Behind the stage name that millions of fans adore lies a young woman with humble beginnings and a fascinating backstory. The journey from ordinary student to beloved idol reveals much about who Arin truly is beneath the spotlight.

Arin's birth name and meaning

Born as Oh Ye-rin on June 18, 1999, the maknae of Oh My Girl carries a name with beautiful significance. "Ye-rin" in Korean translates to "wise jade," reflecting qualities of wisdom and precious value. This birth name seems almost prophetic considering her eventual rise in the entertainment industry. Her stage name "Arin" was carefully selected before her debut, chosen for its melodic quality and memorability among international fans while maintaining a connection to her Korean identity.

Where Arin grew up

The Oh My Girl member spent her formative years in Busan, South Korea's second-largest city known for its beaches, mountains, and vibrant culture. Growing up in this coastal metropolis helped shape Arin's distinct personality. Unlike Seoul's fast-paced environment, Busan offered a more relaxed atmosphere that many fans believe contributed to her grounded nature. Her Busan heritage occasionally surfaces in interviews when she slips into the region's distinctive dialect, much to the delight of her fans.

Arin's school background

Prior to becoming a kpop idol, Arin attended School of Performing Arts Seoul (SOPA), an institution famous for educating numerous Korean celebrities. At SOPA, she majored in Practical Dance, laying the foundation for her future career. Furthermore, Arin graduated with excellent academic standing, showcasing her dedication to both studies and performance training. Several classmates have since shared stories about her diligence and kind personality during those formative years.

Throughout her training period, Arin balanced rigorous practice schedules with her educational responsibilities—a challenging feat that demonstrates the determination beneath her soft appearance. This combination of academic discipline and artistic training ultimately prepared the future Oh My Girl star for the demands of idol life.

She’s the Tallest Despite Being the Youngest

In a fascinating physical paradox within Oh My Girl, Arin contradicts the typical K-pop group dynamics where the youngest member is usually the smallest.

Arin's height compared to other OH MY GIRL members

Standing at approximately 169 cm (5'6.5"), Arin towers over most of her groupmates despite being their beloved maknae. This height measurement places her as the tallest member in the seven-member lineup. For comparison, other Oh My Girl members' heights create an interesting contrast—Hyojung (158 cm), Mimi (162 cm), Seunghee (164 cm), Jiho (165 cm), Yubin (165 cm), and Binnie (166 cm). The height difference becomes particularly noticeable during group formations and choreography, where positioning often requires careful arrangement to maintain visual harmony.

Additionally, this height advantage gives Arin a commanding presence on stage that complements her role in the group. Her tall stature particularly benefits her during fashion shoots and runway appearances, allowing her to showcase outfits with a model-like quality that enhances Oh My Girl's visual appeal.

Why fans find this surprising

Fans often express amazement at this height dynamic because it defies the common expectation in K-pop where the maknae (youngest member) is typically the smallest or shortest. Moreover, Arin's delicate facial features and youthful appearance initially suggest a petite frame, making her actual height even more unexpected to new fans.

The contrast becomes especially apparent in behind-the-scenes content where Arin frequently needs to adjust her posture during group photos. Curiously, her height combined with her status as maknae creates an endearing duality that fans adore—she embodies both the "baby" of the group while simultaneously having a physically protective presence.

This unique combination of youth and stature has become one of Arin's most distinctive characteristics, setting her apart not just within Oh My Girl but also among other K-pop idols. Subsequently, this unexpected trait has become part of her charm, with fans affectionately noting how she literally "stands out" in the group.

Arin’s Spirit Animal is a Rabbit

Among the numerous delightful aspects of Arin's personality, her self-identification with rabbits as her spirit animal stands out as particularly meaningful to both the Oh My Girl member and her dedicated fanbase.

Why Arin chose the rabbit

The connection between Arin and rabbits emerged naturally through her own affinity for these gentle creatures. In several fan meetings and variety show appearances, the Oh My Girl maknae has expressed that she feels a special kinship with rabbits based on shared characteristics. Remarkably, this choice reflects much about her own personality traits—gentleness, alertness, and an innate sweetness that fans consistently notice in her interactions.

Arin's soft features, particularly her expressive eyes and delicate movements, further strengthen this rabbit association. Interestingly, in Korean culture, rabbits symbolize innocence and purity, qualities that align perfectly with the kpop idol's public persona. Additionally, rabbits are known for their quick reflexes and surprising energy beneath their calm exterior—much like how Arin balances her poised on-stage presence with unexpected bursts of playfulness behind the scenes.

On multiple occasions, fellow Oh My Girl members have playfully reinforced this connection by gifting her rabbit-themed items, from plushies to accessories that she cherishes and occasionally displays on social media.

How fans relate to this symbolism

For devoted followers of Arin, this rabbit symbolism has become an affectionate shorthand for understanding her essence. Consequently, fans often incorporate rabbit imagery into handmade gifts, fan art, and supportive messages. Many admirers point out that like rabbits, the kpop idol exhibits a perfect balance of vulnerability and resilience that makes her particularly relatable.

Social media hashtags combining Arin's name with rabbit emojis or nicknames like "Bunny Arin" frequently trend during her birthdays and other special occasions. Fan communities have embraced this symbolism so thoroughly that rabbit motifs have become unofficial emblems in Arin-centered events and celebrations.

The rabbit association has evolved beyond mere symbolism into a meaningful connection point between the idol and her fans, creating a unique aspect of Oh My Girl's fandom culture that revolves specifically around Arin's spirit animal.

She’s Extremely Sensitive to Cold

One distinctive trait that sets Arin apart among Oh My Girl members is her notable sensitivity to cold temperatures. This seemingly minor characteristic has become part of her identity in the eyes of attentive fans who follow the kpop idol's activities.

How this affects her daily life

Arin's extreme sensitivity to cold significantly influences her daily routines and wardrobe choices throughout the year. In fact, the Oh My Girl member frequently layers clothing even during mild weather, often sporting jackets or cardigans when other members comfortably wear lighter outfits. As a result, her personal stylist has adapted her stage costumes accordingly, cleverly incorporating warmer fabrics without compromising the aesthetic appeal of her performances.

Notably, this cold sensitivity affects Arin's living arrangements as well. Her dorm room reportedly maintains a higher temperature than other members' rooms, plus she owns an impressive collection of heated blankets and warmers for year-round use. During winter schedules, the kpop idol takes extra precautions, including heat packs tucked into pockets and thermal undergarments beneath her outfits.

Instances fans noticed this

Attentive followers have documented numerous moments where Arin's cold sensitivity became apparent. During a particularly memorable outdoor filming session for a variety show in autumn, viewers noticed how the Oh My Girl vocalist visibly shivered despite wearing multiple layers while other cast members seemed comfortable. Similarly, fan-captured footage from music show waiting rooms often shows Arin clutching hot drinks between rehearsals.

Perhaps most endearing to fans was a behind-the-scenes moment from their "Dun Dun Dance" promotions where fellow Oh My Girl members jokingly presented Arin with a miniature space heater decorated with rabbit stickers—a thoughtful nod to both her sensitivity to cold and her spirit animal connection.

Throughout concert tours, eagle-eyed audiences have spotted staff members providing additional jackets to Arin between songs, highlighting how her team accommodates this physical trait. This characteristic, although seemingly minor, has become yet another aspect of her personality that endears the kpop idol to her dedicated fanbase.

Arin’s Secret Love for PUBG Mobile

Behind the polished image of a K-pop idol lies an unexpected passion that few fans realize—Arin of Oh My Girl harbors a genuine love for the action-packed battle royale game PUBG Mobile. This gaming interest reveals yet another fascinating dimension to the multifaceted personality of this beloved idol.

Arin's favorite in-game moments

The Oh My Girl maknae particularly excels at stealth gameplay strategies, preferring calculated approaches over aggressive tactics. Indeed, fellow group members have playfully revealed that Arin becomes remarkably focused during gameplay, displaying a competitive side rarely seen in her public appearances. Her gaming sessions typically feature her character navigating buildings methodically, collecting supplies with precision, and occasionally, celebrating rare achievements with quiet enthusiasm.

Interestingly, Arin favors sniper positions when playing squad matches, often supporting teammates from strategic vantage points. This supportive role in gaming mirrors her nurturing personality within Oh My Girl. Throughout late-night sessions after practice, the kpop idol has mastered several challenging in-game achievements, though she remains charmingly modest about these accomplishments in interviews.

How she got into gaming

Arin's journey into gaming began somewhat unexpectedly during the group's tour schedule in 2019. Nevertheless, the demanding travel itinerary left limited entertainment options during downtime, hence mobile gaming emerged as a convenient solution. Soon after, PUBG Mobile became her go-to activity for unwinding between performances.

Over time, what started as casual entertainment evolved into a genuine hobby for the Oh My Girl vocalist. Consequently, gaming provided Arin with both stress relief and a connection to fans who share this interest. Given her typically packed schedule balancing idol activities, acting roles, and brand endorsements, mobile gaming offers a flexible form of entertainment that fits perfectly into brief breaks throughout her day.

This hidden gaming enthusiasm stands in fascinating contrast to her "Princess Arin" image, yet perfectly complements her multidimensional persona that continues to surprise even longtime admirers of the kpop idol.

She Once Got Lost Going to School Alone

Even the most poised K-pop idols have their endearingly human moments, as demonstrated by a charming incident from Arin's daily life that resonates with many fans of the Oh My Girl member.

The story behind this incident

Before becoming a household name, Arin attended the prestigious School of Performing Arts Seoul (SOPA) alongside fellow Oh My Girl member Jiho. The two established a comfortable routine, traveling to school together each morning. This arrangement worked perfectly until Jiho's graduation, creating an unexpected challenge for the younger idol.

On her first day navigating the journey solo, Arin completely lost her way. Without her unnie's guidance, the Oh My Girl maknae found herself wandering unfamiliar streets, eventually arriving late to class. This minor mishap revealed a relatable side to the kpop idol—someone who, despite her polished stage presence, experiences the same everyday challenges as ordinary students.

Interestingly, this incident occurred despite SOPA being a well-known landmark in Seoul's Songpa district. Yet, without her trusted companion, Arin struggled with directions, highlighting how much she had come to rely on Jiho's leadership both inside and outside the group.

How fans reacted

Upon learning about this endearing mishap, fans embraced the story wholeheartedly. Many found it incredibly relatable, with social media comments expressing how this small glimpse into Arin's everyday life made the Oh My Girl vocalist seem more approachable.

Admittedly, this incident sparked numerous supportive messages from the fandom, with many sharing their own stories of directional challenges. As such, what began as a minor embarrassment transformed into a cherished anecdote that strengthened the connection between the kpop idol and her admirers.

Undoubtedly, this story endeared Arin to fans who appreciated seeing the human side of their favorite idol—someone who, despite her talents and achievements, occasionally struggles with everyday tasks just like anyone else.

Arin’s Ideal Type is All About Effort

Unlike many celebrities who prioritize physical attributes, Arin of Oh My Girl has revealed surprisingly thoughtful perspectives on relationships that showcase her maturity beyond her years. Throughout various interviews and fan meetings, the kpop idol has expressed views on romantic partnerships that align perfectly with her authentic character.

What she looks for in a partner

Arin prioritizes effort and sincerity above superficial qualities when describing her ideal type. Rather than focusing on appearance or status, the Oh My Girl vocalist values someone who demonstrates genuine commitment through consistent actions. Interestingly, she once mentioned appreciating people who remember small details about her preferences—revealing how meaningful thoughtfulness is to her.

The kpop idol has expressed admiration for individuals who show dedication to their passions, regardless of what those pursuits might be. This preference highlights her respect for perseverance and determination. Additionally, Arin appreciates good listeners who engage in meaningful conversations rather than dominating discussions, indicating her value for mutual respect in relationships.

Communication stands as another cornerstone in Arin's ideal relationship dynamic. The Oh My Girl member has noted that she values partners who express themselves clearly yet respectfully, mirroring her own thoughtful communication style with fans and colleagues.

How this reflects her personality

These relationship preferences perfectly mirror the qualities Arin herself embodies within Oh My Girl and her broader career. Foremost, her emphasis on consistent effort echoes her own work ethic, having trained diligently for years before debut while maintaining academic excellence.

Her appreciation for thoughtfulness corresponds with how attentively she treats her fellow group members, particularly her close bond with Seunghee. Likewise, the value she places on genuine connection over superficiality aligns with her authentic interactions with fans.

Arin's ideal type essentially represents the qualities she herself strives to embody—dedication, sincerity, and thoughtful communication. This self-awareness demonstrates remarkable emotional intelligence from the Oh My Girl maknae, who clearly understands that meaningful relationships require the same dedicated effort she applies to her professional life.
