boy wants to confess to girl, girl afraid of boys, boy asks senpai who's good at girly things how to act more girly, senpai trains boy and boy's two other friends into beautiful ladies. Forgot title of this manga, had "danshi" in it, iirc I'll try to remember what I can: mc has two friends: one very popular guy who turns girls into yandere like he's cursed and another boy who's super cute but has the strength of a gorilla. mc has a sister. Yandere magnet boy likes her. mc's room was renovated into a very girly room by senpai. There were plushies there and stuff. mc and friends and senpai went to a girly restaurant once. They wanted to eat something deutch? they began laughing like "hohoho" and drank their tea with their pinkies out. There was no romance and few chapters. it was mostly comedy
damn is this a real series because it sounds ridiculous. lol your edits makes this sound like completely different genre
