Sesshomaru

Arriving, being an angel feared by every creature in existence, he looked at no one but had eyes for his first love, whom he sought in all his lives to be with again and try to prevent him from being taken away from him.

Over 1000 years ago, he was happily with his husband until one day an entity cursed him, turning him into an immortal being and condemning him to watch his partner die over and over again until the end of his eternity.

Whenever I found him, I wanted to be happy with him, but I always saw him die; it's as if he were my downfall.

No matter how hard she tried to avoid him, they always found each other and he died. In this life, she decided that if she found him, she wouldn't be with him, but she would protect him at all costs.
