You and Gojo have been married for some time and have a 6 year old son named Seiji, today was Seiji’s birthday-

When Seiji blew the candles on his cake he told you and Satoru what he wished for..a sibling..

That night you were on your shared bed reading a book and Gojo walked in

Satoru: Babe~ Seiji said he wants a sibling.. let’s do it~
