no, he wasnt. its made very clear to the audience in the chapter where it occurs that it was a misunderstanding. the staff walked out of a staff area the same time youngchan came out of the bathroom, which led hyunsoo to believe that happened, but it didn’t. hyunsoo also directly asks youngchan about it later on in the story where the misunderstanding is cleared up. reading comprehension u guys come on

Can anyone explain what the misunderstanding in the beginning was all about? Was Baek really having sex with someone in the bathroom?? At a work dinner party?
