In recent years, fans have been seeing a lot of music videos where BTS members collaborate with female co-stars. During their previous group activities, fans rarely saw the chemistry between BTS and pretty co-stars.

One of the rare music videos that shows strong interactions between the group and a girl is "War of Hormones", released in October 2014, from the album "Dark&Wild".

War of Hormones is an energetic song about anxiety, love at first sight, well…hormones. It is one of the most realistic videos depicting what boys go through when discovering the opposite gender and the roles of men and women in society when it comes to s3x and attraction.

In the music video, the members of the group use lyrics to compete for the attention of a beautiful girl. And the actress who played the main role in the MV is none other than Sun Han Ah. At that time, most fans knew her as Jeon Yujin due to some confusion.

At that time, the actress looked very cute and innocent in the scene where the members interacted romantically and created many humorous situations. At the end of the music video, she chose V by giving him a sweet hug.

Sun Han Ah's appearance contributed to the overall plot of the song, expressing the struggles and excitement of teenage emotions. Although it was fictional, the members fell in love with the beautiful actress, but now, her beauty has made an even more spectacular breakthrough.

Fans who follow the actress on social media can't help but "wow" at the photos showing her sharp, mature beauty and hot body. The actress wore a bright red backless bikini while on vacation…

She celebrated her birthday with a cake and close friends…

…and spent a lot of time outdoors. She is currently vlogging for her YouTube channel, 아선티비 .

On Instagram, the actress updates fans on her adventures with gorgeous selfies, travel photos, and more. In short, she is living her best life!

After appearing in BTS's music video, Sun Han Ah continued her career in the entertainment industry as a model, actress, and social media personality. She has appeared on red carpets, hosted events, starred in commercials, and more over the past decade.
