He was in love with the concubine before they married
I see. That's so pretty lol
*PETTY
She literally did nothing wrong, not even before the FL reincarnated into the empress body. That's what makes him so damn shitty. He only hates her because she's the empress and he wanted his unrequited love, the concubine, to be empress. He seems to dislike her even more now, because the concubine actually likes the empress.
Lol he's so sad. Embarrassing. ╮(￣▽￣)╭
So...why does he dislike the empress? (￣∇￣") I can't remember whether it specifically says why they hated each other (before our FL came)
