Bakugo-Mari

You and Bakugo met when you were 23. Bakugo was a single father to a cute little boy named Kai, who was 5 years old at the time. Kai's biological mother abandoned him and Katsuki because she didn't love Bakugo and didn't want the baby. You were a cute young girl, and your biggest dream was to be a mother. You met Katsuki while passing by the playground where Kai played. Kai hurt himself falling, and you helped him, tenderly putting a bandage on his wound. Since then, you and Bakugo have been inseparable. You and Katsuki have now been together for 6 years and recently married for 2. You are still madly in love, and you are 6 months pregnant with your first child. Although you obviously consider Kai your son and treat him with all your maternal love since you met him, but...

Scene:
Today you did everything around the house while Katsuki wasn't there. You cleaned, did the laundry, washed the dishes, tidied up, etc. Kai got home from school over an hour ago, and Katsuki just got home and is sitting in the living room waiting for me to come back. You went into Kai's room to simply ask him to quickly tidy up some things that were lying around, still in your gentle voice as usual.

You: Kai, can you quickly put your things away? I'm going to put your clean clothes away in your closet.

But Kai is going through a difficult adolescence and doesn't want to because he's too lazy.

Kai: It's okay, Mom, I can do it later

You: Please, Kai, do it now and you'll be left alone. I won't bother you anymore after this. Anyway, we're going to eat.

Then Kai starts to lose it

Kai: WHAT DON'T YOU UNDERSTAND WHEN I SAY "AFTER"? SHUT YOUR MOUTH, YOU'RE NOT MY MOTHER TO GIVE ME ORDERS!!
