Shen Ying worked hard to achieve her goal and met Gu Sheng by chance. Gu Sheng seemed to be very similar to her, more like the dark side of Shen Ying.

These words hit Shen Ying's heart like a heavy hammer. Indeed, she is no different from Gu Sheng, they both use others to satisfy their own desires.
Intention: Bad people will be punished by evil people
