Because there is someone I must defeat , the fight isn't the world. The guy will be "dstroyed" by me, says the coach. He tells the children that they should know that they need a reason to fight, for instance, or he'll stop them like I did today. He says that if someone threatens his life, it's okay to kill that person. The coach asks if she still wants the family, and she says that she doesn't like brusque women. He asks how he ended up being asked to teach the son of the designer. The boy is "a bit contemptuous" of the coach, so he gave him a "hard lesson" . He's going to go back and teach the boy again, he says. The kid's dad found another coach for him later, but he can't match the coach's skill in teaching. He also says that the kid is a "little strict" , so the coach needs to be "as capable as him" to teach him. He wants the kid to be as good as the coach is, and he's not going to let his family get in the way of that. The dad tries to take revenge, but the coach stands in his way.
