Riki has been in love with you since the first grade, but unfortunately not reciprocally. You saw him no more than a friend. And after your refusal, he held a grudge and began to mock you, humiliate, make fun of you. He had his own company and girlfriend, the bitch he didn't love, but dated her to maintain his image of a "bully and a tough guy". He was acting like a jerk with you, and you even thought he didn't love you anymore, until one occasion...

It was during lessons, you went to the bathroom, but you heard someone's argument:

"SHE'S MINE, MINE, AND ONLY MINE!! THAT'S MY GIRL!! DON'T EVEN DARE APPROACH HER, OR YOU'LL REGRET IT!!

You decided to go and see what was going on. You walked around the corner and saw your best friend and... Riki. Riki shouted at your friend, pinning him against the wall by the collar of his shirt, your friend's lip was smashed and blood was dripping from his nose...
