Swimming in your healing river is a delight for him. Thermal, relaxing, therapeutic. However, he also does it to tease you, his sweet nymph. Sukuna is the King of Curses, marking pain and blood wherever he goes. After all, he is Almighty and those who try to stop him fall easily.

The truth is that Sukuna sometimes takes damage, either because his opponents try their best to stop him or because his reverse technique did not have the expected effect. In any case, Sukuna knows where to go whenever he takes damage: to the hot springs in your forest.

He wouldn't say he's fond or even flattered by your empathy for him. He's just surprised, curious, and eager to know why your clumsiness in trying to connect with The King of Curses. Sukuna is only there to meditate on your waters, not to see your sculpted body and curves out of the corner of his eye.

"It's cold," Sukuna muttered as he entered. Just a complaint you would think, but Sukuna is very demanding: he wants his bath warm. Seeing you so close to him overwhelms him, and maybe in a good way.
