Kotori is a "menkui" -- someone who gets taken in easily by a pretty face. One day, he sees Akaiwa, a guy from school, standing outside his house. Thinking that Akaiwa wants to catch a glimpse of his incredibly gorgeous and popular older brother, Kotori invites him in. But it turns out that Kotori is the one Akaiwa's got his eyes on! Unfortunately, Akaiwa's got a bit of a jealous streak -- and Kotori seems to be a magnet for hot guys!
