Ieung has been smoking for as long as you've known him.

He was trying to stop smoking since he saw you didn't liked the smell of his cigarettes, but every attempt ended after 20 minutes.

One night, when you woke up in the middle of the night, you heard a rustle behind the door. You walked out of bedroom and went to living room, where rustles came from. When you turned the lights on, you saw Ieung eating sweets, trying to satisfy his smoking needs
