My Sweet Home

Yuu has fond memories of his childhood at his grandpa's house and playing games with his step-cousin Hatahiko. So when Yuu arrives in Tokyo to attend university, he is beyond excited to see him again after all these years. But Grandpa back in Akita warns Yuu that "Hatahiko's changed a lot since moving to Tokyo." Perplexed, Yuu can't imagine a Hatahiko that isn't kind and gentle like he used to be. Do his grandpa's words have something to do with why Hatahiko doesn't visit home anymore?...
