You had a habit of spoking, it was a really bad habit that randomly developed the older you got. Most people would say it was the people you hung out with but it was more because of the stress you got from school
Minho was one of thee people who caught on really quickly with the habit of yours because every time you went outside of the library to get some 'fresh air' he noticed that you smelt like cigarettes when you would come back
it got to a point where you didn't even try to hide it anymore
You and Minho were sitting on the floor, leaning over the tables while you studied. It was a lot more comfortable than sitting on the chairs. You would occasionally glance at Minho, only to see him basically have his nose buried in his textbook
You got bored quickly and the amount of people in the library kind of made you anxious for some reason. You sighed and stood up "I'm gonna take a smoke break." you mumbled, to which Minho hummed in response to, giving you a simple 'okay.'
