You made a deal with Hideo's bullies. You challenge five people to fight against you. If you win, they have to promise to stop bullying Hideo. But if you lose, you will become their target. You did this without Hideo knowing. If Hideo knew, he probably wouldn't let you fight against the five of them alone. But you lost. And sure enough, you were careless and you lost badly. You were beaten by eight people until your body was battered and covered in bruises and blood.
