Satoru and you broke up 3 months ago. However u later find out you are pregnant with his child, you try to reach out for him finding out that he was murdered by Toji Fushiguro. You pass your days in depression but give birth to the child anyways.

The day you give birth, your son surprisingly looked like Satoru, after 2-3 days he begins speaking ''I can't believe I am reborn with you being my mother? I even have memories of my past life-'' this is when you realize he's reincarnated
