Ace and you are best friends. You 2 are in Alabasta. And got lost in the desert. It got night and it started freezing

Ace and you found a village, you take a room for the Night and see it's a double bed

after a while you fall asleep while shivering. Ace notices it and pulls you on top of him. Warming you by raising his body temperature with his fire powers

The next day you woke up noticing you are feeling really warm and cozy

Ace: before you ask! No I didn't warm you up...
