[Inuyasha] Why Doesn't Burning Winter Count as Burning?

Yukimura Ayaka traveled through time and space to the Warring States Period and became a noble lady. Except for not having a mobile phone, she lives a life here where she can only open her mouth when she reaches for clothes, and it is extremely nourishing. The only thing that gives her a headache is that she has a fiancé named Ren Jian Yin Dao. Renjian Yin Dao is the young city lord of Renjian City. I heard that he has a beautiful face and a gentle temperament. He is impeccable in both appearance and identity. But he was in poor health and suffered from illness all year round. They all said that his end was approaching and that she would be a widow within a few years of her marriage. But there was no way, for the benefit of the family, she had to fulfill this marriage. Besides, it's not a bad thing for Yukimura Ayaka. After her husband dies, she inherits the city, which is really not a good thing. This idea changed after she saw Ren Jian Yin Dao—— The man was even more beautiful than she had imagined, with long black curly hair as smooth as satin, cold white skin like pearls and jade, and bright red and soft lips. He looked like a cross-dressing version of Snow White. It's such a shame that such a beautiful person died like this. So Yukimura Ayaka was bewitched by beauty and felt compassion. She ran around to find doctors to pick herbs for him, hoping that he would survive as much as possible. The hard work paid off. Under her care, his increasingly thin body began to slowly regain its vitality. He began to be able to get down and walk, just like ordinary people. It's just that when his eyes looked at her, there would sometimes be an inhuman hollowness. His warm body was as cold as water, and his cold white skin turned pale and bloodless. Yukimura Ayaka didn't pay too much attention. It wasn't him he she liked, but his flawless face. As long as the face doesn't change, that's fine. However, on a blood moon, Yukimura Ayaka discovered that there was another person in her fiancé's body. No, it should be a monster. A disgusting monster made of rotten flesh, severed limbs and remains, and all the filth of the world. Yukimura Ayaka broke her defense. Where is my fiancé who is so old and beautiful? ! Male protagonist: Naraku, everyone sees the Yin Dao. The setting of two souls in one body, burning the winter. Mission: Let love and warmth soothe the world
