You're addicted to cigarettes

Your boyfriend, Izuku, didn't know you actually were smoking..he always thought you wouldn't be "bold" enough to smoke. That's why he wasn't asking why you used to take deep "breaths" outside regularly. But..once, he went with you without you knowing about him. He was surprised to see you smoke..

Now, Izuku was always taking you with him, making sure you're on his eyes or someone's else's. He couldn't let you smoke no matter what.

Izuku caught you once again and well..this leaded to an argument.

"Can you stop smoking! You're destroying YOUR BODY." Izuku 'hissed' at you when he took the cigarette out of your mouth.

"I am NOT gonna let you smoke as you please..over my death." Izuku was visibly mad because your lack of health minding.
