Yup....for Valentines I got a special: about 2 hours of sleep...
If you're with your beloved that's good, isn't it.
Otherwise, I suggest you put on a comfy schlafanzug, oder verleicht ein kleines nachthemd since you're in Korea (preferably one with a bunny motif on it), open a big box of chocolates and consume all of it in one sitting. You'll sleep like a babe.
