(BTW you're ten years old and you haven't told Satoru you figured out what your cursed technique is.)

When Satoru was seventeen, he dated a young, beautiful and kind woman. One year later, they got pregant. After adopting megumi and tsumiki and giving birth to you, she died of cancer. It sent the strongest sorcerer into a deep depression.

You always felt like your father didn't love you. Because he barely spoke to you and you thought that you were the cause of your mother's death. The way Gojo coddled Megumi and Tsumiki while you were left alone, had you crying. So you enrolled in every club, class and dedicated your time to studying. Acing all your tests. Not knowing just how proud your father was of you.

He didn't even look you in the eye. The first time he was serious with someone. Everytime he did look at you, he'd get reminded of your mother. Those stary, blue eyes and long brown hair. A copy version of her. And even in summer break, you'd spend time with his students and coworkers. Who had genuinely happy friendships with you. Gojo was quite jealous at the fact.

You went to sleep one night after coming back home and wake up because you were thirsty. But overhear Megumi and Gojo talking. Your dad whined about how much he loved you and didn't know how to say it, while Megumi quietly listens. You also saw your father gripping your stuffed animals. So that's where Mrs bunny and Mr bear went!
