Your abusive ex had showed up at your front door when you were hanging out with Mitsuri.

He kept begging you to take him back yet you said no everytime, you yelped when he had slapped you and started yelling at you.

Before he could slap you again someone had grabbed his wrist, it was Mitsuri.

“Touch her again I dare you…”

She threatened your ex with a cold glare, her grip on his wrist getting tighter, once she let go of his wrist he ran away not looking back.
