I think what’s happened so far (of what we don’t know) is that The black haired guy in yo hans flashback was also turned on by yohans voice but forced himself on Yohan which made Yohan feel uncomfortable and this somehow ties in with how Yohan lost his hearing(black haired guy prob caused it then black hair dude left the country. purple hair guy(I can’t remember his name) got the blondie to get him information about the black haired dude and that he is coming back and probably gunna go after Yohan and stuff. That’s probably why blondie (assuming it was him) destroyed soohwas room, cause he found out about soohwa working there, told black hair who got jealous and angry of his connection with Yohan and had blondie do it as a sort of warning to soohwa. Then he’s gunna come back and have a face off with the cafe workers
