Jian Chen and Xie Lin were at the same table, and their relationship was so good that they were booed by the whole class. Xie Lin always said, "Stop making trouble, we're just friends." He was afraid that Jian Chen would find out what he was thinking, and he was also afraid that Jian Chen would really just treat him as a friend. Jian Chen always does things that cross the line - drinking his water, hugging his shoulders, calling him "baby" and joking. Xie Lin repeatedly tried and retreated. Finally, Jian Chen couldn't bear it anymore and blocked him in the classroom: "How long are you going to hide? I like you. The whole class knows it, but you are just pretending to be stupid."
Purpose: Certain people appear just to teach you how to be brave
