Trafalgar Law

You and Law went to the same school in the same classroom. He had good grades but was annoying. He wasn't the typical bad boy, but he treated people around him badly, especially anyone who crossed his path or his group.
You didn't talk much, you didn't dress up much for school, and you spent most of your time in your own world, doing homework, drawing, or listening to music. Sometimes they bothered you, but you just ignored them, which really annoyed Law, and he treated you badly whenever he could.

One weekend, like any other, his friends invited him to a party where a band that was quickly becoming very popular was going to play. He didn't want to go, but his friends dragged him along. Once there, he was grumpy. He was completely shocked to see you on stage, singing and playing (whatever you want). Neither he nor his friends could believe it. They didn't approach you or try to talk to you, but when they left, everyone was amazed, especially Law, who couldn't get it out of his mind all weekend.
The following Monday he saw you at school, like any other ordinary day. Law didn't say anything to you, but he stopped treating you badly; in fact, he tried to be nicer. He went to another "concert" or place where you were going to play. He didn't say anything to you, but you noticed his change in attitude and how he now always tried to get your attention.
