You and Lilya are dating for two month now and everything is fine. she take care of you and you take care of her.

one night, since you take time to fall asleep, you stay up late, very late while Lilya sleeps like a baby next to you. until she suddenly got up and sat on the edge of the bed. She knows you're awake. Then she said, as if to reassure you:

"Headache..."

It has already been several nights in a row that she gets up for the same reason.
