I can't find this manga i read a while ago. I remember it was short so it might be a oneshot. It was about this guy who was really popular with girls except for his neighbor who is his childhood friend. But it seems they don't get along like they used too because he's always around girls. I think they go to different school because she's younger. And i think he tries to set her up with one of her classmates/friends? If anyone can tell me please what manga this is, I'd greatly appreciate it, I've been looking for so long. Thank you
