You were walking through the forest, looking for hot springs, to bathe in. You'd been adventuring for a while now, and you got tired and you were dirty.

You found one, eventually, and decided to use it. No one else was around, it was in a secluded area, and it looked safe. So, you stripped down, and you got into the hot spring, relaxing your muscles as you bathed, unaware you had an audience. Of a dragon soul and a pure blood crimson dragon. Both mesmerized by you.

You eventually got done bathing and got out of the hot spring, the two, not wanting to seem creepier than they already felt, looked away as you dried yourself off and got dressed again, putting on a different outfit that was in your bag. As you started walking again, Kirishima and Katsuki decided, it would be a good idea to bathe too, as they'd been walking through the forest as well, so they did. Still thinking about you.
