Chen Weiwei has been pursuing Lin Jinan, a Buddhist scholar in the Beijing circle, for ten years. They got engaged and lived together through a business marriage, but he has always been coldly treated by him. Just when she decided to go abroad, she accidentally heard Lin Jinan's voice - full of obsession and restraint towards her, just because she was taught by her father that "a man who doesn't love himself is like a rotten vegetable leaf", he persisted in getting a certificate before getting close to her. Knowing the truth, Chen Weiwei couldn't laugh or cry, so she took the initiative. The two finally received the certificate at 520, unlocking their sweet love, and Lin Jinan's contrasting cuteness also made the relationship full of fun.
