"Resident Playbook" has become a very famous Kdrama right now and many viewers will notice and love the GenZ group from the Obstetrics and Gynecology department of YulJae Medical Center. Along with O I-yeong, Nam Gyeong, and Sa Bi, the only male obstetrician-gynecologist, Eun Jae-yi, has also become a beloved character by viewers. Eun Jae-yi is a character who debuted as a member of the idol group "Hi Boyz" before becoming a doctor. Hi Boyz, a group created just for the drama, consists of three male members, Eun Jae-yi (Kang Yoo Seok), Topkey (TXT's Yeonjun), and Bin (TXT's Soobin). This group was created specifically for "Resident Playbook" and did not exist in reality.

However, a scene of the Hi Boyz's song being played was included in a karaoke outing scene in the previous episodes and currently, their song "When the Day Comes" is gaining popularity, leading to a real-life debut performance for Hi Boyz on Mnet's M Countdown. They didn't stop after filming for the drama, and they actually recorded the song and released a music video. As an OST, this song has even charted on domestic music charts. Actor Kang Yoo Seok is practicing choreography with TXT's Yeonjun and Soobin for their live performance on Mnet's M Countdown. For viewers who have been watching the drama, this is like a happy gift, as the fictional group Hi Boyz, created specifically for the storyline, will be performing in front of their eyes.

This unexpected turn of events has delighted fans, who are now witnessing the blurred lines between fiction and reality. The song's climb on the charts further solidifies its appeal beyond just being a drama OST. Kang Yoo Seok's dedication to practicing alongside seasoned idols like Yeonjun and Soobin demonstrates his commitment to delivering an authentic performance. The synergy between the drama's narrative and this real-world music debut has created a unique promotional buzz. It's a testament to the drama's influence that a fictional group can achieve such a tangible level of success. The anticipation for their M Countdown stage is immense, with fans eager to see their beloved "Hi Boyz" truly come alive. This move also highlights the increasing trend of dramas extending their impact into the music industry. The collaboration with popular K-pop idols has undoubtedly amplified the song's reach and visibility. This initiative not only entertains but also fosters a deeper connection between the audience and the drama's universe. It's a clever way to keep the drama's momentum going even after its episodes conclude.
