The wishes of the Hello Girl (fandom name) have come true. 'High Boys' (Yeonjun, Soobin, Kang Yuseok) will take the stage for a music broadcast.

On the 16th, the Mnet 'M Countdown' team revealed in a phone call with 'Dispatch', "High Boys will appear on 'M Countdown' next week. We are discussing the details."

'High Boys' is a fictional boy group from tvN's show 'Sometime Soon: Wise Ghost's Life' (written by Kim Seung-hee, directed by Lee Min-soo). Eom Jae-il (played by Kang Yuseok) is presented as a member of this group.

Yeonjun and Soobin from 'Tomorrow X Together' also play members of 'High Boys'. They made a surprise appearance at the end of the broadcast on the 9th and performed their hit song 'When That Day Comes'.

The three learned the choreography for 'When That Day Comes' for this scene. It is reported that choreographer Choi Young-jun directed it. They also filmed related videos such as a performance video and a release greeting.

This raises expectations for a 'Second Seon-up-twi' craze. 'Seon-jae Up Go Twi' is a band song featured in the show that swept the main music charts. 'Shower' ranked 14th on the Melon annual chart for 2024.

The popularity of the song 'When That Day Comes' is notable. Performed by Tomorrow X Together, the song was released on the 11th. As of the 16th, it reached 36th on Melon’s 'Top 100' and 19th on 'Hot 100'.

Meanwhile, the 'High Boys' performance can be seen on 'M Countdown', airing on the 22nd.
