Amy~sama and Zane got in a fight

Amy~sama had just gotten home from work shethad taken over Kawaii~chan's last shift of the day. She finished early what she saw when she got home broke her heart "What the H*LL!" She screamed seeing Zane and Kawaii~chan making out

Zane and Kawaii~chan turned to face her

"I TOOK OVER YOUR SHIFT SO YOU COULD MAKE OUT WITH MY BOYFRIEND!?!" Amy~sama shouted angrily at Kawaii~chan

"A-amy~sama! It's not what it looks like!" Zane said

"DON'T EVEN START THAT!" Amy~sama shouted "GET OUT OF MY HOUSE!!" she shouted pointing to the door

When they refused Amy~sama walked over to them pulling them by their wrists to the door before shoving them outside. She knew Zane always left his key on the table when he was home so she locked the door knowing he couldn't get in.

Amy~sama sat against the door and started crying

Something similar could be happening to your OC or they could be there for Amy~sama
