俺を好きなのはお前だけかよ

Amatsuyu 'Joro' Kisaragi, convinced he's the protagonist of his own harem comedy, accepts invitations from two girls, upperclassman Cosmos and childhood friend Himawari, expecting confessions. Both ask him to help them win his best friend Sun-chan instead. The only girl actually interested in Joro is Sumireko 'Pansy' Sanshokuin, a plain-looking library regular whose knowledge of his true scheming personality runs deeper than he'd like.
