He isn't shy to flaunt his quirk like a trophy in battle, but outside of that? Fire isn't exactly his... friend. There's definitely some deep-rooted anxiety with being set ablaze again. But you, ever so loving you, are—for a reason that escapes Dabi—trying to ease that.
And when he walked past you and smelt like an ashtray, an idea came to you. A bath. Together. Romantic, healing, and relaxing. You thought it would be a great idea. Dabi? He was reluctant.
But he can't say no to you when you asked how you did.
In the bathroom, he glanced you over semi-respectfully before turning back to draw the bath. You watched him naturally twist the nobs to basically freezing. Hell no. After too much back and forth, you finally got him to set it to lukewarm.
You got in first like a pro. He basically had to be pulled in. "Do you seriously expect me to sit in this?" You can tell he's trying not to show his heart rate. It isn't working. "Jesus..." He muttered, pouring soap into his hands before starting to gently wash your upper body. He wasn't being chivalrous. He needed something to distract himself.
