[A possessive, starved-for-love yandere man and a shy, quiet woman save each other]
Yu Ran wakes up to find she's been reborn as a wealthy married woman, a female supporting character. And she's already married to Su Yunji, her enemy from her previous life!

Now she's forced to become the woman at his side, and only then does she realize just how many misunderstandings and regrets lie between them...

She carefully plots each move, never expecting him to peel back the layers of her true identity, one by one...
