She shouldn't have been entangled with Lian Cheng after He Sitian married him.
What?
Is she pitying He Sitian or feeling sorry for Lian Cheng?
Or does she think the person she has always admired has finally become imperfect, and now she has the chance to give charity, to pity?
And even "sacrifice" herself, putting herself on the moral high ground, covering up the fact that she's competing for the brother-in-law... In the original plot, He Sitian didn't directly become dark, it's because she was kind enough!
Even when the novel world was infected with a virus, forcing He Sitian to become dark, she didn't immediately target He Siyu.
Instead, it's He Siyu, who on the surface acts all "deep sisterhood", but secretly always regards He Sitian as a rival.
She not only wants to snatch her sister's lover but also wants to seize her parents' attention, the compliments from friends and relatives around, and the praises and envy of everyone!
