I feel like I read this but can’t recall (Ｔ＿Ｔ)
https://www.mangago.me/read-manga/why_are_you_so_kind_to_everyone_except_me/ kind of similar troupe but this must not be it since i don't recall reading the drinks part
It’s not this one but thanks anyway!
Searching for a manga I don’t really remember the plot but I just remember one specific part that the mc thinks his classmate hates him but he secretly likes him. The mc buys coffees for the group mates but gets the hater a sweet drink thinking he likes sweet drinks and tries to be nice but then he takes the mc’s coffee so the mc thinks he’s fucking with him on purpose. Vague but worth a shot!
