I don't think I'm the bad woman who destroyed Sang Shixi's family, because I've looked up Sang Shixi's current wife online these past few days.
She also comes from a noble family, and has been married to Sang Shixi for three years already. I guess she doesn't get his love, so this Madam Sang's reputation is quite unpleasant. There's a constant stream of negative news about her, like young pretty boys coming and going from gigolo bars and so on.
Because her family background is so strong, I estimate that Sang Shixi probably doesn't have any feelings for her either, so he turns a blind eye, and that's how their marriage has persisted.
In my view, Sang Shixi has long wanted to divorce her, only he lacked a powerful reason to do so.
So now it's convenient to use me as an excuse to push the boat with the current.
