I agree with you, but I don't think he can do much to punish purple because of who she is (she's a princess of another country(?)).
Like how he only made her watch her servant being tortured (to death?) and how he visited her place after she threatened to commit suicide if he doesn't come.
I dont like the seme he is too harsh. Yu er is always suffering so much please here prince take some of my brain cells and see the truth that purple bitch hasn't learned her lesson
