The day his sister died, only black remained in Tang Sirui's world.
In order to take revenge, Tang Sirui was willing to accept her most hated identity - the most shady illegitimate daughter of the Qiao family, to fulfill Qiao Qingchen's engagement with the Gu family.
Gu Yue, Tang Sirui's fiancé, is also Tang Sirui's immediate boss.
He is calm and self-possessed, and regards Tang Sirui as the perfect tool to solve family troubles.
He wanted to regard Tang Sirui as Qiao Qingchen's substitute, but the longer they got along, the greater the difference between Qiao Qingchen and Tang Sirui. In the end, Gu Yue was completely confused as to whether he had ever loved Qiao Qingchen.
Tang Sirui, wearing a gentle and well-behaved mask, "accidentally" appeared in front of Gu Yue, asking Gu Yue to pay attention to him, and successfully entered the Qiao family through Gu Yue, avenging his sister.
Tang Sirui deceived everyone, including Gu Yue.
Tang Sirui was also soft-hearted and did not want to drag Gu Yue into the water.
But seeing his enemy crushing him easily, Tang Sirui said to Gu Yue:
"I'm going to start using you!"
Gu Yue just smiled contemptuously: "I can't ask for it!"
