Cute story about a boy with terrible luck who whenever he gets in a relationship the bad luck gets transferred to them. One day the seme sees him getting dumped in the middle of campus, and later finds out they're neighbors, and decides with very little hesitation to ask him out. They struggle against the bad luck for like all of the manga, but it's all cutesy and they love each other so they don't let it get between them. The cutesy art-style and the height difference made this manga feel a little shotacon-esque but oh well
