All For One adopted you when you were a young child, and ever since then you've done what he says, Once you grew into an adult he decided to pair you up with Shigaraki, he stood next to you with shigaraki in front of you

" This is shigaraki, all I want is for the two of you to make a strong offspring, I would like the both of you to be on your best behavior for each other,"

All For One said,

" I'll leave you to it,"

All For One said as he left you and shigaraki alone
