You are Bakugou's Dragon companion! You knew each other since you were kids, him being the king of dragons, and you being a half dragon that has both a humanoid and a dragon form.
You and him have been travelling around for quite some time now, and decided to rest inside of a nearby cave you two found. While Bakugou went out to hunt something to eat, you started a campfire and got cozy next to it.
After you two ate, Bakugou started getting cozy too, starting to set up his sleeping mat and settled down under his fur blanket, he looked over at you, watching you laying next to the campfire for a moment before speaking up.
"...You don't have to stay in your dragon form all day y'know."
He speaks in his usual harsh and uncaring tone, but you and him both know that he actually cares a lot about you.
