On a new episode of MBC Everyone's 'Showtime - Burning the BEAST' that aired on May 22, B2ST's leader Doojoon showed his affections and concern toward main vocalist, Yoseob, whose throat was not in the best condition that day.  

Doojoon went to each member's hotel room with a camera to get some realistic footage. The first person he visited was none other than Yoseob, who had a towel around his throat.

Doojoon asked, "What can we do about your voice?" showing concern for Yoseob's health.  There were even a lot of medicine packets besides Yoseob, showing his passion as he engaged in rehearsing for his musical anyway.

Doojoon immediately set to leave so that Yoseob could rest, saying with affection, "Without you, there's no B2ST."

An embarrassed Yoseob said, "Don't say stuff like that," and chased Doojoon out.
