Jiang Yimeng has a habit of folding useless poems into paper airplanes and throwing them into the school's abandoned old water tower. She thought it was her secret base, but she didn't know that every paper airplane had been picked up by Zhou Lin and kept properly.
Zhou Lin had always been secretly in love with the girl who was seriously folding paper airplanes under the sunset, but she didn't dare to get close because of the distance Jiang Yimeng deliberately kept. In order to be able to talk to her, he deliberately "destroyed his image" in the school-wide announcement of criticism, just so that he could stand with her.
