Black Chain
She’s the one who awakened him as a dragon and put him on the throne hoping that he will accept her as his mate but he abandons her in the end and she kills herself and woke up to her being back in time in hopes to change the future not knowing that he was the one who turned back time just to have her as his mate
The Dragon Prince's Ill-Mated Betrothal
The one who killed MC was the first prince. MC belive the one who killed her is the 3rd prince, because the maid who bring the tea with poison told her, that the tea was sent by the 3rd prince. The 3rd prince belive she commit suicide because that was what a maid told him, so her death wasn't investigated. Dragons cannot kill their mates and cannot be involved in any way their death anyway, because if they do they get 2 curse as a punishment and one is that their mate never reborn as their mate, and the other is something what I didn't understand so they lose it forever. But the soul going to reborn again and not disapper. The first prince killed his own mate, Princess Sarah (he ate her O.O) he thought she betrayed him with the 3rd Prince (there was some gossips, because Sarah helped him many times, and 1st prince having trashy personality, she cry many times that it's so hard to keep his love, and he didn't trust her, but she Loved him with all her heart), then she reincarnated as the 3rd prince mate and she got killed by him once more /he only noticed that she is Sarah a few days prior of her death/. Originally he wanted to creat the same scenecario, what he went throught, he wanted ML kill FL becasue of jelousity. The first prince belive MC is Sarah because her blood and flesh having the same taste as his mate. His revenge was never valid because Sarah never betrayed him. MCs reincarnation was deliberately stopped, by the 3rd prince, so his brother cannot use her as a tool for revenge (he deliberately made FL and MCs relationship worse) he didn't want her reincarnated until the 1st prince is alive/he plan to kill him/, her body was in a safe place and it cost 110 years to break down the door what protected her body, and the first prince get to know she didn't reincarnated beacause there was interuption with a very old technik in the reincarnation cicle, then he disposed the third prince magic and MC reincarnated. /The dragons having the ability to possess other people body -Zeph is going to be possesed by the 1rd prince, levi is ocassionally possessed by the 3rd prince/ The greatest taboo is to kill their mate but the king is loving the 1st prince so mush, that he never haved the thought to let the 3rd prince to succes him.
