Am i stupid or nothing that indicates he's a red flag was shown?

yapping ahead







from what i understood, his reaction to mc's confession was almost like "okay ill agree to whatever you say" BUTT not out of his own feelings. he "admits" he likes him aswell, sort of as a way to get the MC to trust him and then goes on to kissing him and whatnot which was fine. its just the end scene that sort of confirmed that something slightly bad might be upcoming when he threw up coincidentally after their kiss (interpret it how you like but majority are seeing it as in he's A. disgusted by the kiss or B. some manipulative zombie or infected person who's trying to take advantage of MC) ofc theres no way of knowing since i dont think there are any raws rn

sorry for the yappp but i hope this explains how some ppl view his behavior as "red-flagged" ^^

again this is just speculations theres no way to tell if hes actually gonna be a not so good character until chaps drop, but we shall pray and wait
