Jian Li, a clerk in the administration department, was forced to take the blame for her stepsister because of her stepmother's plan, and accidentally got involved in the "contract marriage" situation of Gu hope, the president of the Gu Group. Gu hope, who has a bright and smiling appearance, hides the gloomy scars of childhood loss, and regards Jian Li as an "emotional test subject"; Jian Li, who is cold on the outside and hot on the inside, breaks his defenses with tenacity and sincerity. The two heal each other while dealing with family infighting, workplace conspiracies, and public opinion siege. In the end, Gu hope tears up the contract and is honest and sincere, and Jian Li also learns to embrace love and warmth as she grows up. The exciting points focus on the heroine outsmarting her stepmother/stepsister, fighting back against workplace oppression, and using her professional skills to defeat doubters; the male protagonist's identity reversal from "controller" to "wooer", and the emotional tension between the two from mutual testing to two-way redemption.
