chicken or beef?

Kotaro (a.k.a Kota), a healthy, burly high school boy, fell in love with a beautiful girl at first sight! But the girl turns out to be his childhood friend, Tsukasa, whom he thought was a boy when they were little kids...? "Are you really a girl!" Tsukasa may seem like a pretty girl, but she still acts like a little boy, and Kota pledged to be the same friend he was back then…!? It's a troubled confusion between love and friendship. Can he really change her feelings into LOVE! (Source: NicoNico Seiga, translated)
