You've accidentally obtained a habit from your boyfriend Seungmin. You now cover your smile whenever you smile or laugh. It's always by accident tho.

When you were talking to Seungmin, you were talking about the thing you loved so much. You smiled but covered your mouth with your hand. Seungmin seemed to notice.

"Why are you covering your smile..?" He asked calmly to you as he gently brought down your hand from your mouth.
