Throughout BTS’s music career, their music videos have rarely featured female actresses, especially after the LOVE YOURSELF Highlight Reel. Since then, the group has almost completely removed female roles from their storytelling. Instead, they shifted toward more abstract and artistic imagery, moving away from traditional male-female romance narratives.

Because of that, music videos such as Boy In Luv, Just One Day, and War of Hormone — which featured female actresses — have become precious relics of BTS’s early era, a period when the group portrayed intense teenage love stories on screen. In particular, during BTS’s two most recent concerts at Estadio GNP Seguros, the group performed “Boy In Luv” and “Just One Day” as surprise songs, reviving nostalgic memories for longtime fans.

When “Boy In Luv” returned to the stage, the female lead role originally played by Go So Hyun (also known as Go So Mi) quickly drew major attention from fans once again!

In the MV, Go So Hyun played a high school girl with a cold, calm, and somewhat distant beauty. She appeared as the center of attention — the type of female lead who made every boy desperately try to confess his feelings to her. One of the most memorable moments was when Jin seemed to completely “lose his mind” over her, even singing to her and giving her a rose.

However, 12 years have pαѕѕed since the filming of the “Boy In Luv” MV, and just as BTS’s appearances have changed over time, Go So Hyun has naturally changed as well!

Through photos shared on Instagram, she now appears elegant and gentle, embracing a clean girl aesthetic while still radiating her own unique charm and a bright, captivating smile. Compared to her rebellious high school image in “Boy In Luv” — complete with a school uniform and bleached blonde hair — her current style is completely different. Still, fans believe this “upgraded” version of her is absolutely perfect.

Her charm became even more evident when she appeared on the popular dating show "Noona Is a Woman to Me", where she became the most talked-about female “catfish” contestant. Her striking visuals, femininity, fashion sense, and personality quickly attracted the male contestants on the show. She even became the center of a “love square” involving Gu Bon-hee, Kim Moo-jin, and Kim Sang-hyun.

By the end of the show, she ended up choosing Kim Sang-hyun — the person viewers believed suited her best. A special episode later revealed that the two continued seeing each other in real life. Go So Hyun shared that because they lived close to one another, Kim Sang-hyun would often pick her up after work every day. At the time, netizens jokingly commented that “BTS’s first love had found a new love.”

Not only does Go So Hyun possess enviable visuals and style, but she also has an impressive career of her own. Before working with BTS, she had already placed in the Top 5 of кσяєα's Next Top Model Season 3 in 2012. After collaborating with BTS, Go So Hyun went on to appear in several other music videos, including “Love Satellite” by Clazziquai Project, “Bonnie & Clyde” by DEAN, “Inconvenient Truth” by INFINITE, and “Blossom Tears” by Leo of VIXX.

However, since she originally began her career as a model, she later focused primarily on fashion modeling and commercial modeling for various brands. Go also signed an exclusive modeling contract with Esteem Entertainment for many years.

In “Noona Is a Woman to Me,” she was also introduced as academically accomplished. She stu∂ιєd Computer Engineering at Ewha Womans University — one of the most prestigious women’s universities in кσяєα — further reinforcing her image as both intelligent and dynamic.

With all of these advantages, it is easy to understand why she was once considered “BTS’s first love,” and why all eyes are still drawn to her even after 12 years. Fans continue flooding social media with admiring comments about her: "She’s gorgeous", "No wonder BTS fell for her. Her visuals still insane", "She aged like fine wine", "Still looks like a movie нєяσιиe", "Literally the definition of elegance. Main character energy forever", "She’s even prettier now",...
