High schooler Kakeru Tanaka's fired up about getting his first-ever girlfriend! He wants someone cute, and younger than him... But his dreams are shattered by a new guy at school, Akane Itsuzumi, who's a disturbing combination of gorgeous and terrifying! Akane wants help with something, and Kakeru's bad at saying no, so off they go to somewhere private, where a blushing Akane suddenly sniffs Kakeru and tells him he's... the one! And so begins a rom-com about the awkwardness and confusion of teenage love! (Source: Renta!)
