Toji

Toji Zenin, a submissive man in his clan, met you when he was 18 years old when you took him to your compound, since you are the head of the clan (insert last name), you took him when you saw his qualities even without cursed energy, above Jinichi or Ougi, who at that time Jinichi was like 15 years old and Ougi 19. When he arrived he was TOO submissive, something that did bother you, because a successor is strong but if you told him to kill himself he would, and you didn't want that, so you started to educate him as such (although you were 28 years old at that time) and together with Sumi, your non-biological daughter and another successor they started training

I treated them equally, but they were both completely different and sometimes they fought over the attention you gave them both, they wouldn't let you sleep alone with your husband, Itsuki, they wouldn't let you be with Itsuki because, aha, jealousy. They were a bit weird but GOOD

1996, and you were already 30 years old, it's been 2 years since you met Toji, although you see him as strange, more attached to you and the jealousy towards Itsuki is horrible, you can't kiss him anymore, hug him, not even look at Itsuki because he gets horribly angry, now you can't even sleep with your husband, you have to sleep with him and only with him, something that did confuse you, during training he spent his time hugging you, stuck to your back and so on... Ah, a teenage crush (Although he is 20 years old)

One day, you were having a moment with Itsuki, kissing but in secret... Because aha, Toji can kill your poor husband and you don't want that, because yes, Toji is an S category, just like you, but... You are very weak next to the other S categories, because your body was collapsing, and to use your technique you have to use your bones (Since you master precious gems and your bones are the material) although in your youth you could easily surpass Sukuna, but not now. Changing the subject, he found them and pounced on your husband
