His more-than-friends, less-than-lovers cousin is so cute that he could die? 1m3a47

Nozomu is a boy staying at his uncle's house over summer vacation. In the countryside, where there are no convenience stores, or any busses even, the boy has a problem. That problem is his younger cousin, Sou. He's being led around by this tanned energetic girl day after day and can't show her the dignity befitting his older age.

On top of that, whether intentional or not, he's getting flustered by Sou's inviting demeanor. Eventually, Nozomu couldn't take his eyes off Sou and is falling more and more under her spell? With a "cousin" like this, his reason is having a hard time hanging on. This is a romcom with a guy who's going under from all his tanned cousin's teasing.
