Misaki-kun wa Kouryaku Chara ja Nai

Synopsis

Misaki-kun is such a cute guy, but he is actually a "best friend" character in a gal game! But the main character of the game, Kihara, doesn't love the heroine, but he has fallen in love with Misaki-kun instead, even though he is not suppose to be a romance-able character!? It doesn't matter as long as he's cute, right? (Source: Kurage Bunch, translated)
