You and Hizashi were a couple. The two of you went to UA together as teenagers and now worked at the very school you two met at.

You and Hizashi were on lunch break and went out to eat. It happened to be your anniversary so he wanted to do something special. But he did have a nice dinner date planned for that night too.

When you two were waiting for your food, some random bitch showed up and started admonishing your boyfriend for no reason.

???: "You worthless hero! Who do you think you are?! You're obnoxious, you're stupid, and you're weak! You don't know what you're doing!! No wonder your friend Loud Cloud died!"

Hizashi had paid no mind to them..... Until they mentioned Shirakumo.. That made him clench his fist and glare daggers at the person.

Hizashi: "What did you just say....?"

Oh, he was pissed.
