This is a story about redemption and being redeemed, and finding true love amidst misunderstanding and rebirth. The male protagonist Lu Jingchen was once the light that pulled the female protagonist Su Nian out of the quagmire of her original family, but he was separated due to a misunderstanding. They reunited many years later, but fate caused Su Nian to "accidentally die". The grief-stricken Lu Jingchen found a stand-in Lin Sheng who looked similar to Su Nian, and projected all his guilt and longing for his deceased wife onto her. Just when Lin Sheng was gradually immersed in this false tenderness and thought she had found her home, Lu Jingchen's heart-wrenching words on her birthday completely broke her heart. And at this moment, a "Su Nian" with future memories came back...
Personally, I think it's quite pretty.
