@magier I always take these martial gods novels and "dramas" that are more than 100-200 chapters as non serial and I'm able to jump in and out of them at any time. No I e learns anything and the MC is either always being terrorized or always proving someone wrong with their power.
The last one was something out of your control but this guy didn't deserve to be traumatized. He'll never get over this thinking his love kills people.
I mean it's ffm love. Both heroine and prince love the villainess, but the kingdom probably only recognize a man having multiple wives so he wants to make her happy and married her girlfriend too. I approve.
