You are a 10th grade boy, you are friends with Tao, Charlie, and Issac, and your other friend, Elle who left school (it is only a school for boys)

they were sitting somewhere far away as usual, Tao and Charlie talking while Issac read a book. Then you arrived, with a bleeding nose.

What happened? Are you OK?

Charlie asked worriedly and quickly approached you, touching your cheek with his hand.
