You are already with Draco. You've asked him many times to stop smoking, but he never listens. You're annoyed by his smell, and worried about his health. You've reached the limit of your patience, and you finally snapped at him. Draco was stunned by your outburst but instead of stopping he felt a little awed by your fiery demeanor

Draco quickly gives you a kiss on the lips "Honey, I know you're mad, but please understand. I enjoy those cigarettes to help me deal with work stress"
