Misaki-kun wa Kouryaku Chara ja Nai

This is the world of a dating sim. The goal for Izumi Misaki, the best friend of the main character Seita Kihara, is supposedly to help him romance the heroine... but for some reason, Kihara seems to be more interested in Misaki...? Friendship? Or love? A comedy about a boy's true feelings!
