Lol I also for a brief moment have a thought it might be the brother because of Hyung part, but then I remember the comment "it's turning me on" and also the part they were invasive with his sexual life. Unless it's going to incest "he's not my blood brother" route I doubt it's his hyung
i def don't think its his brother! theres way too many things pointing at it not being the brother but i do think his brother might show up in a non weird way
Santa is most likely the creepy stalker! He's the only one who would know mc name and that he's been freaky w/his friends... Now it could be the unknown brother but #doubt
