Based on Kobayashi ga Kawai sugite Tsurai!!, which is a shoujo manga by Ikeyamada Gou. The game has an exclusive scenario unseen in the manga, and was constructed by Ikeyamada herself.

Megumu gains a new love interest in the game-exclusive character, Elio Falcone, a beautiful Italian boy. As a result, Elio and Sanada Aoi- (Megumu's original love interest) will be rivals and the plot will largely revolve around how this will affect Megumu and Aoi's relationship. There will also be Halloween, Christmas and Valentine's Day-centric subplots.
