Key decides to do a good deed while shopping on Taemin's birthday

Because you are Key's jagiya, and Key's jagiya knows everything.

  ” When he ran into you, the two of you found yourselves chest to chest, and face to face, nose to nose. Your eyes widened, as did his. You could count every fleck of gold and brown in his eyes, count every eyelash. You could feel goosebumps growing on your arms. You could feel him breathing against your face.”

Scorned by his own girlfriend on Christmas Eve, Key finds a different sort of happiness and perhaps the true meaning of the holidays, at Asan Medical Center.

When Key begins feeling the pressures of idol life, you decide that maybe a good natured joke will do him some good. The results don't turn out quite the way you imagined.
