Why do I feel that Chayeon was already in his sense b4 he took bath and was jst pretending. He was checking if Jeongyoon have feelings for him too and when Jeongyoon hugged back he looked at him, smiled and said I knew it. Later when he was left alone he got up and got disappointed. Probably hes angry bcoz after every intimate encounter Jeongyoon keeps going back acting like nothing happened.
