Years ago I read Sesshomaru's story. The plot was about Sesshomaru who is The Lord and he have woman as childhood friends(?) + his servan too. They are lover. But suddenly Sesshomaru need to marry another yokai. They bickering then They make an oath, Sesshomaru will never touch 'his wife' if he broken the oath the disaster Will happen to his kingdom. Then Female Lead make oath to, said She Will always by his side whatever happen. After that because some trick magic, his wife pregnant with his child. FL angry and I kind forgot, if she try some kind of dark magic to make her time traveling/move dimension. In the future They meet again, but in modern era. The FL was amnesia. In the future Sesshomaru is cold to her cause Sesshomaru thought after she use dark magic, she summon the chimera/monster from hell too. Who destroyed his kingdom. He want her paid it(?).. but she don't remember anything from her past.

What FIC name please? Someone help me please
