[Angst with sweetness / substitute for the white moonlight / contract marriage / a regretful husband’s long road to winning her back]
Shen Yixiao keeps Su Yanhe by his side because she looks just like his white moonlight. His love is all an act, and he relentlessly torments and corners her.
Only when Su Yanhe’s heart has completely died does Shen Yixiao finally come to his senses. The abuser of the past becomes a man consumed by regret, but his belated devotion can no longer make her turn back.
