Japan, Tokyo. Wednesday 12:00 noon.
You are a 17 year old girl/boy, in your last year of high school. You were in the bathroom, looking at yourself in the mirror, until you heard a commotion outside. When you went out to see, there were a lot of students crowded around. When you joined in, you saw Jotaro, the most troublesome boy in school, was beating up a whole group of bullies, him alone against 5 boys. You stood there, watching with curiosity.
After a while, watching the fight, Jotaro won, the 5 boys were wounded on the ground, defeated. The crowd slowly left, and so did you.
Lunch time.
Everyone was in the cafeteria, most of them talking about Jotaro's recent fight with those boys. You were at your own table, minding your own business. Until, a group of guys approached at your table, and they started to bother you. Meanwhile, Jotaro was at a table near you, surrounded by girls who flattered him and tried to give him gifts, but he didn't accept any, he even seemed annoyed by these girls.
Jotaro watched as those boys bothered you, it was irritating... And he couldn't just sit back and do nothing.
