"Mister, mister, are you ok?", Rey shook the handsome young man on the side of the road that seems to have been been sun poisoned and collapsed, she has been trying to wake him up for some time but without success, so she pulled him under a tree (with difficulty) to try to cool him down. She also tied his black hair to cool off his neck. He seems to be a traveler as he wore some strange clothing that looks a bit fancy for this town and it's no wonder that he would get ill, he was fully covered in such dark clothing while at that time of the day.

Luckily, a villager with his wagon came passing by and helped Rey to bring the young man in her home, which was also the only clinic in that village. The young man was huge, there was no way she could have carried him back on her own.

When Rey had him settled in an available bedding. She first took off his top to help him cool off, it took her a bit of time to do it as he was quite big. Luckily he was wearing another cloth underneath, at least he will still be wearing something else, it's not that it bothers Rey to see a man's torso, she is a doctor for goodness sake, however, thinking about it made her blush. She then wiped him down with a cold cloth, then she applied some cooling medicine to his exposed skin. Hopefully, he would wake soon.

The young man finally woke when the sun has set, slowly, he took in his surroundings, there was a young woman with her hair tied in three buns checking on people who seemed to be ill, when she glanced at him, she gave her a big smile.

She approached him and took the cool cloth on his forehead and dipped it in a bucket beside him, after wringing it dry, she placed it back to his forehead. "You're finally awake mister, you got lucky that I was on my way home when I saw you, you were quite ill".

"I…thank you, miss?", the young man purposely hang those words so the girl can fill-in the gaps.

"I'm Rey, I'm this village's doctor", then she gave him another big smile.

"I'm Kylo", the young man introduced himself out of courtesy. "I should really head back, I'll be a lot better if I go home,'' he continued. He looked around a bit and found his top hanging on the side of the bed and grabbed it, he slowly sat up on the bed and tried to stand but he was unable to steady himself and almost fell if it weren't for Rey's helping hand.

Rey suggested to wait for a few more minutes but Kylo stood again and headed to the door on wobbly feet. He was quite stubborn and Rey got a bit annoyed so she quickly grab her medicine bag and followed him, ready to help when needed, she was curious too on where he was gonna go on foot.

However, Rey suddenly panicked when she caught up to Kylo as he sat on the edge of the well just behind her house. When she grabbed his arm to stop him, it was too late. He had already jumped and she was dragged along.

When Rey came to, she was in a luxurious four post bed with black satin sheets and Kylo was sitting on a chair beside her.

"You shouldn't have done that" was his first words to her.

"Where am I?", Rey asked while looking around the room. The room itself is brightly lit with a fireplace, marbled walls and floors, and a bookcase at the corner. It's quite simple but also elegant, in a way. She moved to sit at the edge of the bed to face him.

"You're in the Underworld", Kylo nonchalantly answered. Rey gawked at him for a second and she took another look at the room, it didn't look like underworld to her, well, it's not like she knows what the underworld actually looked like.

She skeptically raised one of her eyebrows and looked at Kylo, "And you are?"

"Kylo"

"No, I mean what are you?", Rey rephrased her question so he can better answer it.

"Ah! I'm the god of the underworld", he answered again casually as if its the normal thing for him. Then he took a cup from the bedside table and started drinking its contents, whatever it was it looked like it was warm.

Rey, on the other hand, tilted her head in wonder. "So, are you an idiot?"

Kylo spluttered his drink from her question, then Rey continued to clarify, "I mean you had been sun poisoned and collapsed at the side of the road when I found you. What kind of a god gets sick from the sun and a god of the underworld at that, isn't that kind of your thing?".

Kylo gently put down his cup back in the bedside table. "How rude. As you can see around you, this place is a lot cooler than what you may believe, I haven't been on the surface for so long that my body didn't adjust very well from the heat."

Rey was still tilting her head as if analyzing the man in front of her. "For how long have you not been in the surface?".

Kylo tapped on his cheek to think of his answer, "Give or take a thousand years or so, does that really matter?''

Rey nodded and ignored his question, then she looked around her and realized that she doesn't have her bag with her so she opted to ask Kylo about it, which he answered by pulling the bag from beside the table. Rey took it and took out a small tin container that she popped open, then she dabbed a little of the ointment onto her hand and started to reach out to Kylo's face, but he grabbed her hands to stop her.

"What are you doing?", Kylo asked looking at her hand.

"You don't look like you've recovered enough, this is just some cooling medicine for your skin." Rey looked determined to apply the medicine and that she would not let him argue, so Kylo lets go of her and let her do what she wants. She gave him a smile before applying the medicine on his neck and forehead. Her gentle hand felt nice on his skin. When she was finished, he unknowingly leaned towards the girl to try to follow her hand but caught himself right away. The girl was oblivious as she was focused on closing her container, then she put it on the bedside table.

"If your skin is still red, apply that every 2 hrs at least", she tapped the container, then continued, "Now if you don't mind, could you tell me how to get back home?"

Kylo was stunned, it seems like she was just there like a doctor to her patient. Her reaction when he said he is the god of the underworld was not what he expected, he might have expected her to scream or run, but never in his immortal life would he ever think this girl would call him an idiot and now she's asking how to go home, as if it did not register to her that she is in literal hell. Kylo suddenly burst into laughter.

Rey raised a brow at Kylo, confused why he was laughing, "What's so funny?"

Kylo stopped laughing and gave Rey a smile, "You're not what I expected, honestly''. He snickered then gestured to follow him.

Rey promptly followed him then tapped his arm, "Can I still go back here? I still need to check your progress".

Kylo was surprised again at her question. "You are something else Rey, I'm a demon, yet you treat me like one of your patients".

"You are my patient", Rey replied with a shrug.

"Is that all I am to you?", Kylo whispered that Rey barely heard it. So she asked what he said, but he just shook his head and lead Rey to the fire place, with a wave of his hand, the fire was put out and the fireplace expanded twice its size that it would fit her.

Kylo took Rey's hand to help her into the fire place and assured her that it will not be hot. "When you go back to the surface you will be back on the top of the well", then he turned and took something from a box, a ring, and handed it to the girl. "If you want to go back here, wear that ring and go back down the well, you will go straight here in my room."

As she stood in the fireplace, she reminded Kylo "Every 2 hours". Kylo just smiled and nodded at her and with another wave of his hand she disappeared and the fire place was back to how it was.

Rey was back on the surface with a smile on her lips as she went back to her house to treat her other patients.

Kylo went back to his chair and was about to pick up his drink again when he sees the tin that Rey left behind, he took it in his hand and looked at it fondly, a smile plastered on his face, laughing again at what had just occurred.

Notes:

This fic is based on a Manga I'm currently reading "Colette wa Shinu Koto ni Shita", its about a human doctor who attends to Hades when he got sick because he became allergic to the sun.

I also have a version of this in another fandom, I just wanted to try if I can rewrite it.
