A car accident on a rainy night turns the cool and resilient Su Wanting into the brightest light in the life of Yang Xiao, a roguish, handsome, and obsessive young man.
Two years later, the gears of fate turn once more at a university in A City. Yang Xiao comes to repay his debt of gratitude and pursue the feelings in his heart, carefully making his way into Su Wanting’s world. His passion burns like fire, but just as she begins to trust him, her words, “I’m grateful, but it isn’t love,” shatter him completely.
When Su Wanting’s family is struck by disaster and her hypocritical senior finally reveals his true colors, she has nowhere left to turn. Yang Xiao presents her with a marriage contract, claiming to save her while truly seeking to possess her. “Sign it, and I’ll help you.” For three years, she must fulfill every duty of a wife. To save her father, Su Wanting enters an apartment at Xinghewan, and steps into a cage disguised as love.
Living under the same roof, he tries to make up for his guilt with endless affection, but the ugly circumstances of their relationship’s beginning still wound her. As his obsessive possessiveness clashes with her independent dignity, and the contract’s expiration date draws closer... will this marriage, born of an unequal bargain, end in reconciliation, or will they let each other go and find peace apart?
This is a struggle over love, dignity, growth, and redemption. Watch as the stubborn, cool moonlight illuminates the dazzling galaxy of his obsession, until they finally find the true freedom and peace that belong to them both.
