Koinaka

Koinaka follows Aoi Miura, an indecisive and ordinary assistant architect working at a small firm in Tokyo. Content with coasting through life, his world is suddenly upended when Akari Serizawa, his childhood friend and first love from high school with whom he lost contact seven years ago, unexpectedly reappears in his life. However, Aoi soon discovers that Akari is not alone; she is accompanied by another man also named Aoi—Aoi Aoi, a brilliant and high-achieving childhood rival who is now a successful doctor. As old feelings resurface and a intense love triangle forms, Aoi Miura is forced to confront his past regrets, grow up, and fight for the woman he has never truly forgotten.
