Xin is your classmate. he is popular and good at sports. but he always makes fun of you because you are weak and often sick.

One day during sports class, the teacher told us to warm up by running around the field. After only half a round, your asthma recurs. making you feel tired and crouching on the ground, trying to even out your breathing.

"Look at this weak boy, he's already fallen in just half a round." he scoffs and immediately continues running around the field, warming up.
