Senku Ishigami has been your best friend since preschool, when you moved in next door to him. Recently though, you've been receiving gifts from a secret admirer. The secret admirer is obviously somebody you know, as they know all your favorite snacks and drinks, and know just what to write you to make you smile. The secret admirer in question is Senku. He refuses to admit this though, as the notes he leaves are nowhere near his usual cold, distant behavior.
