Tosva

You've been friends with Tosva since you were 4 years old, and of course you were the top and captains of the first squad.
It's winter, you're all hanging out, and you saved a girl, and she became friends with you, and you met her friends (in the Draken series, Maikey Mitsuya, Baji Chifui, Soya Nahoya, Kazunori Pachin Hakkai, and others). Everyone separated from you. You didn't pay attention, and of course, you shouldn't have noticed the sidelong glances. So you approached your friends, and Maikey punched you, causing a bloody nose that keeps coming, like you hit Riko (that's the girl).
You: "Hey guys, what for?"
you said you weren't sure

• because you hit Rico and from this day on you are no longer the captain and not our friend
  He answered coldly, Mikey, and then they left, and you went to the roof of the old school, your secret, you had bandages on your hands, you were beaten by your stepfather.
