i remember that it just made fun of all the bad tropes, like ecchi stuff happening only to the airheaded childhood friend and turned the tropes around like she actually is good at her studies than the other love interest who is totally dumb. the mc and childhood friend like each other but either of them dont know of the others feelings. the latest chapters had a tomboy who had older brother complex.

Is it Osamake: Romcom Where The Childhood Friend Won't Lose?
