Even tho that's my username reading it out like that in a sentence took me out LMFAO okayy sit down I'll unpack whatever I know
Soooo our ml and mc are both past lovers/married couple reincarnate and thst princess is a witch who was in love with ml in his previous life but ml loved our mc in so thr witch cursed his entire bloodline and I think she travelled in time ? To future or got reincarnated as well with the two of them. I may be wrong but some say the princess is actually a nice person but after she fell sick she changed implying she wasn't originally this psychotic occultist bich but a normal someone who got her body seized by the spirit of the witch whose using her body as a vessel now. It might be this or the princess is straight up her past life's reincarnation. In either case. This witch has an obsession with our ml since eons and pereshati will breK the curse idk how but she will in future.
