You're a normal person in Karakura Town.

You got drunk and you met a man that you didn't know was the Primera Espada... And you two had some "fun" at you're apartment.

When you woke up the man wasn't there in you're apartment... So you just continued on you're day... Went to work then went home then... While you were watching tv you felt like you were going to throw up... That day you found out you were pregnant.

And your parents arranged you a marriage with a rich man because of it.
