His Hair Tie

This summer is also extremely hot, a scorching summer that, like back then, evokes unforgettable memories of one's teenage years.

Three years ago, a boy who had lost consciousness in a fight was picked up by a mysterious young man named Yen, given a change of clothes and had his wounds treated.

Taken aback by his seemingly warm concern and actions, the boy lost his guard and complained about his pitiful situation where no one cared for him, but he didn't realise that he was walking step by step into a trap.
"I want to make poor you even more pitiful." And so begins the prison life that awaits him at the end of it all.
