Gu Qingtang, the daughter of a wealthy family, ranks first in the grade with her "frail and sickly" character. She is the white moonlight who is the heart of all the boys in the school. However, on the first day of school, the school bully Shen Yan publicly tore up the anonymous love letter she had hidden in her desk - it was handwriting that he deliberately imitated with his left hand, just to catch this Black Lotus who appeared to be Buddhist but actually used everyone as pawns. The two went from being bitter enemies who exposed each other's past to being involved in a polyamorous whirlpool: a hypocritical best friend secretly changed Gu Qingtang's recommendation quota, Shen Yan's "old love" suddenly returned to China to intervene, and even a wealthy elder secretly arranged a marriage. While Gu Qingtang uses his high IQ to fight back against Green Tea, he uncovers the broken past hidden under Shen Yan's "violent school bully"; Shen Yan uses coquettish tactics to tear away her "sick and frail" disguise. In the game between you and me, the two people who were separated due to family misunderstanding finally face their true feelings and complete the two-way redemption of reunion on the night of the college entrance examination results release.
