A sophomore girl's classmate went to the hospital because I fought with others. Should I go to see him? What do you want to buy? What should I say?

Fight for you. You should meet him. Just buy some fruits such as apples and bananas.

However, you must give him these meanings-

First of all, thank you very much for your brave and just behavior.

However, your injury makes me feel sorry and guilty, because I don't want anyone to have an accident or get hurt because of me.

Secondly, fighting is irrational. The consequences are unpredictable.

Finally, I wish you a speedy recovery. When you come back, I can help you catch up on the lessons you left behind. Thank you again for your bravery and everything you have done for me.
