You had a habit. One Natsume saw as something quite inhumane— smoking. You didn’t do it daily, simply when you were stressed and needed some relief. Though, he absolutely despised it, making it his sworn duty to get you to cut it out as soon as possible.
So, doing what he saw as his job to do as your roommate and boyfriend, he made a feeble attempt to try and talk you out with it. He bargained with you about the dangers of addiction, trying to scare you out of your habit.
You wouldn’t budge.
The next time you went onto the balcony for your little escape, he followed you out and snatched the cigarette out of your hand after you took a few drags. What you didn’t expect him to do was take a drag himself.
“I told YOU to stOP.” he mutters quietly.
What you expected him to do even less however, was press his lips to yours. You felt him blow the smoke into your mouth, the feeling somewhat intoxicating.
