Since the beginning of the show, the audience thought that HI-BOYZ, Um Jae Il's idol group, was just a myth. However, in Resident Playbook (2025) episode 9, finally the true form of HI-BOYZ, along with their signature song, was spilled.
After HI-BOYZ's MV was released on Stone Music Entertainment, many fans created content as if the group had debuted in 2011 and had now disbanded. It's no wonder that many netizens who didn't watch Resident Playbook (2025) are wondering who HI-BOYZ really is.
For those of you who are curious, check out their profiles! HI-BOYZ is a fictional idol group born in the Korean drama Resident Playbook (2025). The group consists of seven members, one of whom is Um Jae Il (Kang You Seok) aka Um Jay, an OBGYN resident doctor at Jongno Yulje Hospital.
In Resident Playbook (2025) episode 9, it was just revealed that TXT's Yeonjun and Soobin are members of HI-BOYZ. The appearance of the two idols under HYBE Labels as cameos in Resident Playbook (2025) has been awaited. However, the audience did not expect that they would only appear in the HI-BOYZ MV.
According to Park Yu Hyeon (Park Yoo Hyun), one of the gynecology patient guardians in episode 9, HI-BOYZ debuted on February 4, 2011 and achieved their first win on June 2, 2012. Unfortunately, HI-BOYZ suddenly disbanded on December 28, 2013.
Fans have calculated Um Jae Il's age when he first debuted with HI-BOYZ. If Jae Il is 28 years old in 2023, then in 2011 he was only 16 years old. So how old are Yeonjun and Soobin? In addition, HI-BOYZ has an official fan name, Hello Girl.
They also have a special slogan, which is when Hello Girl says, "Hi, My Boyz.", then the HI-BOYZ members reply, "Hi, Hello Girl." Uniquely, according to the audience's prediction, it turns out that Kim Sa Bi (Han Ye Ji) is Hello Girl, precisely the ninth fan of HI-BOYZ. However, Kim Sa Bi does not idolize Um Jay, but Top Key.
Stone Music Entertainment released the MV "When the Days Comes", the debut song of the idol group HI-BOYZ on Tuesday May 13, 2025. After watching the MV, many viewers claimed to understand why HI-BOYZ disbanded.
The reason is because of the seven members, only Um Jae Il, Yeonjun, and Soobin are always in the spotlight. In addition, the outfits they wear and the background of the "When the Days Comes" MV shoot are also too simple.
For your information, the song "When the Days Comes" (2025) is actually sung by TXT and is the official OST of the Korean drama Resident Playbook (2025). Although in the MV it looks like lipsyncing, Um Jae Il is able to perform live as he showed in episode 9 while doing karaoke.
Um Jae Il once said that BTS is his hoobaenim, because HI-BOYZ debuted in 2013. Wow, that means Yeonjun and Soobin are actually BTS sunbaenims. Who's following HI-BOYZ fans' POV on social media?
