セクハラブラザーズ 愛されすぎ編

Since the surprise conjoining of their families seven years ago, Yukio has grown to love and care for his new, bigger, louder family. For a while, things were peaceful... until Masumi's cousin Ringo comes back to follow through on his declaration of love made seven years ago: he is going to marry Big Bro Yukio. Just when Masumi is content with how he and Yukio have grown close, his cousin/rival appears and threatens his ease. But what Masumi should have been worrying about wasn't Ringo at all...
