Atarashii Onee-san

When Yuu’s distant (and attractive!) relative Amane moves in with his family, things between the two of them couldn’t be more awkward. But Yuu is determined to make her feel welcome. Just as their relationship seems to be improving, Yuu’s best friend expresses an interest in Amane. There’s no way Amane would be into him though… right?
