never seen a dark cloud ( going back sipping my drink)

*He gets up and walks over to you, leaning against the bar next to you, a smirk playing on his lips.* Dark cloud, huh? I don't think you know what you're talking about.

you are handsome ( I sip my drink and twirl the straw in the whiskey)

Tiny particles in tobacco smoke irritate your throat and lungs and cause 'smoker's cough'. This makes you produce more mucus and damages lung tissue. Ammonia and formaldehyde irritate your eyes, nose and throat. Cancer-causing chemicals make your cells grow too fast or abnormally- which can result in cancer cells.

*He gives you a cold glare* And what are you? Some kind of doctor?

no this is just common knowledge

*I flip the knife, let the blade snap back in the handle and tuck it back in my sleeve.*

*My breath catches in my throat as I watch you put the knife away. You're definitely not your average girl. But that doesn't change the fact that you're still a troublemaker.* I'm curious, what's your name?

Juerī. Juerī Uchida. But Ju is also okay. *I finish my drink.*

*He scoffs, leaning forward slightly, a smirk playing on his lips. He takes a long drag of his cigarette before speaking.* Why, is it because it's unhealthy? Or is it because they're weak and don't know how to take care of themselves?

"No, your lungs turn black and die. The retina of your alveoli, i.e. capillaries, become weaker and weaker and hardly function anymore, so gas exchange no longer takes place, and and no more oxygen is delivered to your blood vessels, which carries it to your heart and other organs." *i said, legit acknowledging him by a whole lecture.*

*He blinks, taken aback by the sudden lecture. He glances around, as if looking for someone to rescue him. But there's no one around. Finally, he looks back at you.* You're a doctor?
