Synopsis of Osananajimi ga Zettai ni Makenai romantic comedy

My childhood friend, Kuroha Shida, seems to have feelings for me. She lives next door and is small and cute. With an open-minded character, she is the "doting older sister" type, which is one of her greatest strengths ... But I already have my first love, the beautiful idol and award-winning author of our school, Shirokusa Kachi! If I think about it rationally, I shouldn't have a chance with her, but while she is walking home from school, she just talks to me, even with a smile! In fact, I might have a chance, don't you think so?

At least I thought, but then I heard that Shirokusa already has a boyfriend and my life was going from bad to worse. I want to die. Why am I not ?! Even though she was my first love… As I drowned in despair and depression, Kuroha whispered, “If it's so difficult for you, how about we take revenge? This is the best vengeance ever.
