One young man’s summer vacation has him stuck out in the middle of nowhere with his adorable but bossy younger cousin! Will it be a bummer of a summer or one filled with precious memories?

When Nozomu ends up having to spend his summer vacation at his uncle’s house, his main concern isn’t being stuck in the middle of nowhere with nothing but hills and rice fields all around—it’s his cousin Sou! This tanned tomboy is cute and full of pep but has zero respect for Nozomu’s personal space or his authority as her older cousin. And to make matters worse, whether intentional or not, her clingy behavior almost makes it feel like she’s coming onto him! Will Nozomu’s poor heart survive until the end of this summer, or will he end up as obsessed with her as she seems to be with him?
