The story follows Kazuto Imazaki, a student in middle school is always bullied for being gullible, stupid, and worst of all - making fun of his single father. He tried to endure it his entire middle school life, until one day he got framed for instigating a fight during his third year - but in actuality was protecting someone. Which left him distraught for days on end. During one of those days, he thought about ending it all - But that all changed when he was approached by a girl named Ayasaka Minami, a first year high schooler at that time. Noticing his solemn state, she gave him a free bento that she sells. At first Kazuto tried to pay for it, but she insisted that it is free of charge.

Will something blossom between these two?
