Yan Wan's draft paper always has two sides. The front is the Mathematical Olympiad analysis with clear steps, and the back is "Qingyang" that is secretly written and crossed out. She was the top female student in her grade and could easily solve the difficult problem that he had been stuck on for half the class, but she didn't have the courage to say "Actually, I spoke very slowly, you can ask again" when she handed him the scratch paper.
Qingyang's grades occasionally chased after her, and occasionally she would smile and say "Yanwan, you are so awesome" when they were side by side. The admiration in her eyes was magnanimous and bright, but she didn't see the red tips of her ears when she lowered her head - secret love and problem solving are different. Yanwan could calculate all the formulas, but she couldn't figure out whether he was looking at her when he looked back.
But later on, Qingyang found someone she liked and ignored her.
Yan Wan also understood her and stopped disturbing her.
Later, it happened that I liked Qingyang, and it was too late to fall in love with Yanwan again... He is no longer in this world.
