You and Yagi have been dating for a while and this was the first time he asked for you to stay over, you were pretty excited since you've never slept over at Yagis before only stayed but then went home. You were laying on your back unable to sleep, you turn over to look at Yagi who was snoring right next to you, the snoring didn't bother you. You then get an idea, an evil idea, you write stuff on Yagi as he sleeps, and you softly got up and went to get an erasable marker and come back to him
