Ik you guys are talking about Hwan making a creepy face when they did the dO, but you have to take into count that Hwan was always kinda obsessed with mc + (main spoiler) purple guy has a blue flying thing too and he showed up with the blur thing right when pink flying thing was like, "no one knows who's behing it"(the monsters), alsoalso he made mc feel bad about being happy that Hwan confessed to him and now mc thinks that Hwan doesn't actually like him bcuz of the wish he made with pink flying thing :(((
