Urakata Chara no Aoki-kun ga Love-Come wo Seisu Made.

Ideal love cannot be realised. As an unknown writer, I can only write delusional rom-com novels. And yet... "Teach me about love, Sensei!" It seems that Ayase Mai, the heroine from the drama club, has mistaken me for some sort of love master. I started researching rom-coms with her in order to bring out her ideal love... "Even if the lines are embarrassing... I'll do my best!" In the end, isn't that just actor coaching!? Guiding a youth rom-com as a backstage character!
