[TITLE] Please Help

I've been finding this doujin for a while now but I can't! Anyways, the context is about boy1 being dared to confess to this big girl which they found completely unapproachable(idk if she's a bully or rumored like that or smth) but when he did confess to her she accepted it, which is not what they are expecting, also boy2 who dared to boy1 to do it was the one who secretly likes her, so that's all, please help and thank you!
