sorry for the false hope bc i dont think either of these are right but:
http://www.mangago.zone/read-manga/kimi_ga_kirai_na_koi_no_hanashi/ - the girl isnt shy and she doesnt wear glasses, but there is a scene where the ML helps her bc the class wasn’t listening
http://www.mangago.zone/read-manga/i_became_the_class_representative/ - the girl is shy and she wears glasses, but i dont think there is a scene like the one you described
good luck in finding it!! i SWEAR ive read one like what you described but i cant remember what its called either… i’ll continue to search if i have time lol
I only remember a few scenes from it, but one of the main ones was the shy/quiet glasses girl got elected as the class representative and is trying to get the class to decide on a theme for their festival/classroom thing. Popular boy offers to help the girl in exchange for either becoming his girlfriend or sex (can’t remember if it was ecchi or not). Please help me!
