Zhang Ning met Zhao Yunkun in her first love, which was both sweet and catastrophic. When they met again 8 years later, she realized that what she had lost was not her first love, but the beautiful years that should have belonged to them.
The thing that Zhao Yunkun regrets most in his life is falling in love with Zhang Ning too early and falling in love with him when he was not able to protect her.
Concept: Love requires management, not just impulse.
