A video was recently posted of a situation that occurred during the ending of a RIIZE concert, in which a fan threw a bra onto the stage, shocking the group members. Fans have been amused by the members’ embarrassed reactions, in particular members Eunseok and Sungchan, who can be seen in the video trying not to laugh and attempting to keep a straight face.

Fans commented, 

"I can feel the embarrassment even now lol"

"The difference between Eunseok and Sungchan's reactions is really funny. There's one who is visibly surprised and then there's one who just blinks while trying to pretend it's nothing"

"I've never seen Eunseok so flustered before, haha"
