The next day, the coach tells the student that he will meet him at 6:30 a.m. on floor 68. The potion that the coach has given the student can help him sleep better, and it will also help him get rid of fatigue from training, he says. He tells her to wipe her mouth first, because if she eats too much, she will damage her stomach. The coach tells her that he cannot force her to train, but if she thinks she is exhausted, she can choose not to train and take a rest. He says that if she is not happy with her coach, they can always swap coaches anytime. The student says that the potion works well, but it hurts too much to dodge all of the obstacles. She tells him to wait for her the next morning, when she will be able to train whenever she likes.
