Wana ni Kakatta Villain-kun

The story follows Chihiro, a high school girl determined to help her friend Yuzu achieve her first love. One day—sparked by the idea of a double date—Chihiro approaches Akamine, a boy who happens to be on good terms with the object of Yuzu's affection, and asks for his cooperation in bringing the two together. However, he flatly turns her down, retorting, "Why don't you just leave them alone?" and "You're such a busybody." The story follows the romance that unfolds between these two individuals, whose personalities and mindsets couldn't be more incompatible.
