Since BTS confirmed their return with their fifth full-length album, scheduled for release on March 20, fan discussions have largely revolved around various theories surrounding the album. Recently, speculation has emerged suggesting that the upcoming fifth studio album could in fact serve as a sequel to BTS’s first full-length album, Dark & Wild.

This theory has gained traction due to several notable coincidences: both Dark & Wild (released in 2014) and the fifth studio album feature 14 tracks; both share a release date on the 20th (Dark & Wild was released on August 20); and they even follow a concept described as “a journey from darkness to light, from wildness to stability, from a starting point to completion.”

When fans look back on the group’s first full-length album released a decade ago, a flood of memories inevitably resurfaces. Among them is the track “War of Hormone,” included on that album. “War of Hormone” is an energetic song about anxiety, love at first sight, and—quite literally—hormones. It is often regarded as one of the most candid portrayals of what young men experience as they begin to explore the opposite ѕєχ and confront social perceptions of masculinity, femininity, ѕєχuality, and attraction.

Interestingly, the music video for “War of Hormone” was filmed in a relatively simple setting yet followed a fairly dramatic storyline. It also stands out as one of the rare BTS songs to feature a female co-star with frequent and intense on-screen interaction. In the video, the members appear in a school bad-boy style, displaying exaggerated expressions and impulsive reactions to the girl’s charm. They even use the lyrics themselves as a way to compete for her attention as they surround the beautiful girl.

Meanwhile, despite the chaotic confessions unfolding around her, the girl mostly continues to walk, stand still, or cast brief glances with a neutral expression. It is not until the very end of the music video that she chooses V and gives him a sweet hug. Although the storyline is fictional, fans were nonetheless left with a strong impression of the elegant young woman surrounded by the idols.

The female lead in the music video was actress Sun Han Ah. Some fans may recall her under the name Jeon Yujin; however, that was a misconception. More than ten years later, she has once again drawn attention for her increasingly mature and striking beauty, as well as her toned figure. It is not difficult to keep up with her latest updates, as she is currently active as a content creator on Instagram and YouTube.

and spending plenty of time outdoors. Fans have also noticed her fondness for fishing through numerous photos and vlogs documenting her sea fishing trips.

Following her appearance in BTS’s music video, Sun Han Ah continued her career in the entertainment industry as a model and actress. She also tried her hand at hosting events and appearing in commercials. However, in recent years, she appears to have found her niche as a KOL and social media content creator, focusing her career in that direction.

Looking at Sun Han Ah today, fans cannot help but marvel at how much the girl once pursued by all seven Bangtan members has matured in both beauty and presence. Many are also happy to see that she has built a stable career and is now enjoying a fulfilling life. One fan commented, “The girl BTS chased back then has grown into a glamorous and successful woman. And BTS are no longer a group of bad boys flirting with girls, but accomplished men with remarkable careers.”
