The teacher is sick, so the class is going to be called "self-study" instead of "math" . The students are ecstatic, and the sports captain leads them to the courts. The sports captain tells the students that the school is holding a sports carnival and that they should submit their application forms by the following Wednesday. Cang cang wants to participate in the 100 meter race, but he's worried that he'll be tired by the time he reaches the finish line. He wants to try something else, like meditation, but the professor tells him not to worry, because there are so many people who are not good at running that he should try it out. The professor says that he gave up running his best, but that's because his legs are too long. He tells the couple that they are super cute, and that he wants to be single forever.
