Introduction: Mu Yan: Maybe we were living in two worlds just a second ago, but from now on, everything about you only belongs to me. Yiyi: If I hadn't met you, where would I be?
For Lin Yiyi, the most unlucky and luckiest combination in the world is to meet Mu Yan, fall in love with Mu Yan, and Mu Yan also loves her.
To Mu Yan, Yiyi was the most beautiful love interest she had ever seen in her life, no, even in the next life, because he believed they would meet her again.
