[Contractual love + scheming sister + contrasting juniors + mutual redemption] Xie Qinglan has a problem - her scumbag father is urging her to get married so much that he wants to send her to marry a strange man, so she sets her sights on her direct junior, Jiang Che, at a dinner party: clean and obedient, handsome and from a poor family, so suitable for being a "contract boyfriend". Xie Qinglan pushed through the contract and smiled with ease: "Fifteen thousand, act with me, for half a year." She thought it was a good deal that killed two birds with one stone, but later, Jiang Che, who had always been meek, pressed her down on the desk and whispered in a low voice: "Senior, this time... I want to sign a life-long contract."
