Oh, Come On, Is There Really Such a Disease?

I came into a dungeon to earn money.

I'm an archer, but the dungeon I'm heading into is low difficulty, so it shouldn't be too hard.

As soon as I entered the dungeon, I saw a goblin.

I drew my bowstring and cleared the first room.

That was thanks to Fragment Arrows, which had been developed to take out multiple monsters.

By the time I reached the third room, I sensed someone coming in behind me.

The warrior hesitantly made me an offer.

"W-Would you like to party with me, if you don't mind?"

I hadn't come into the dungeon looking for anything particularly valuable, but the other person looked like a complete beginner.

Though they were a warrior, clearing this dungeon alone would probably be too much for them.

Having reached that conclusion, I nodded and said,

"Sure, I'd love to. I'm alone too, so I needed someone to fight on the front lines."

Though it was a party formed on the spur of the moment, this was a relatively safe dungeon that even beginners could clear without much trouble, so we finished it quickly and left.

The warrior approached me and thanked me.

"This is my first time playing this game, so I don't really know much. Thanks for helping me. Can I add you as a friend?"

"Sure, I don't mind. Enjoy the game~"

After accepting the friend request, I turned off the game and browsed the internet. When I got bored, I shut down the computer and lay down.

Maybe it was because I'd stayed up all night gaming again, or maybe it was because the weather was cold, but my whole body hurt.

I was prone to catching colds, so I didn't think much of it.

I lay there fiddling with my phone until I fell asleep.

My body felt hot, and it was hard to get up.

But since someone had called, it would be kind of wrong to go back to sleep... right?

"Cough... Hello...?"

"Uh... it's me. Are you sick?"

"Yeah... I'm fucking sick... My whole body feels hot, like I've come down with the flu..."

"Right, then I guess we'll have to meet later. I'll hang up. Get plenty of rest~"

"Yeah, see you next time~"

When I checked the time on my phone, it was already nine in the morning.

What time did I fall asleep...? There was no doubt I'd slept for at least twelve hours.

No wonder I was hungry after sleeping that long, hahaha...

When you're sick, you're supposed to eat porridge, right...?

I ordered some porridge from a franchise near my home through a delivery app, then turned on my computer.

Honestly, even when I'm sick, using a computer or phone is the most efficient way to kill time.

Isn't a phone what most people, myself included, fiddle with for hours, forgetting even to blink?

When I was young, I spent so many nights on the computer that my 2.0 eyesight plummeted below 0.6, and now I can't even make out the face of the person in front of me without glasses.

Since I only have simple myopia, I can manage daily life without glasses, but... that may be fine inside the house, yet everything outside looks blurry when I take them off, and it makes me so anxious that I can't go out without them.

Most people who wear glasses are like that too, right...? Contacts would let me live without glasses, but with a face as ugly as mine, taking off my glasses would make me look even more of a mess...

Oh, it looks like the delivery's already here—the doorbell just went ding-dong~.

Come to think of it, how many people order porridge at nine in the morning?

Most people only think of porridge when they're sick; practically no one eats it normally...

While playing games after eating porridge, I opened a message from the user I'd become friends with yesterday.

They had thanked me for helping them yesterday and asked whether I played any other games.

I play one FPS, but since I was sick, I said I'd have to take a break for a while and sent the reply.

"Living alone is really hard and lonely..."

By the time I finished gaming, it was already five in the afternoon... It wouldn't matter much if I went to sleep now, right...?

My body hurt. The phone kept ringing like crazy, but I couldn't come to my senses.

My body grew heavier and heavier as I drifted into sleep.

"...Hoon! Jihoon! Wake up!"

"Ugh... who is it...?"

"It's me, me...! Your friend, Hyunwoo!"

"Huh... What are you doing here?"

"You said you were sick this morning, but you weren't answering your phone at all, so I got worried and came over. Your fever hit 40 degrees, so I called 119."

"Ah... thanks..."

Then I noticed the doctor standing beside my friend.

The doctor spoke to me when he saw I'd regained consciousness.

"Hmm... The test results don't look like an ordinary cold or case of the flu. It seems to be some unusual illness, but I don't know what it is. How about staying in the hospital for a while and undergoing some tests?"

"I don't mind, but... if my hospital stay gets long, my living expenses might become a problem..."

"Don't worry. We'll see what we can do to arrange support from the hospital."

"Yes, please do."

After reassuring my friend and sending them home, I was admitted to the hospital and decided to undergo tests every day.

The doctor had said it didn't seem like a normal illness, and since I was being offered financial support, I had no reason to refuse.

And the next day after I was admitted... I had to hear something that struck me like a bolt from the blue.

"W-What...? I heard that wrong, right?"

"No... You heard correctly. I was surprised too, but if the illness continues like this, there's a possibility your sex could change."

"Th-Then what about my ID... What about my family and friends...!"

"As for that... your resident registration number and name would be the only things changed on your ID, but regarding your personal relationships, the most I could do would be to prove that whoever you became was the same person as you before the change."

"Honestly, even hearing it from you, this is hard to believe. If I stay here a little longer, the results will... become clear, so I'll wait a few days."

"I understand. Then enjoy your lunch, and please call if anything happens. I'll see you tomorrow."

The doctor left my room, and thirty minutes later, lunch arrived.

People often say hospital food tastes bad, but since I rarely ate proper meals in the first place, I thought this was perfectly fine.

Around three in the afternoon, a man wearing a black suit came to visit.

"Hello, Mr. Jihoon. I received an urgent report from the hospital and came to provide support from the government."

"Ah... Is that so?"

"Yes. This is only a hypothetical situation, but we're going to provide assistance on the assumption that you really do become a woman."

"I understand. But will I have to pay for anything, or is there anything I'm expected to cover?"

"You shouldn't have to pay anything. All you'll need to do is think of a name to use later. You'll have plenty of expenses, including clothes, so we'll support you in those areas as well. I'll come back tomorrow afternoon."

"Yes... Thank you."

Sigh... The doctor and that man both think I'm really going to become a girl? Could that actually be possible?

Is it scientifically possible? I've seen posts claiming that the Y chromosome will eventually degenerate and disappear, but that's supposed to happen several thousand years from now...

If the Y chromosome were actually degenerating right now, I wouldn't be the only one this was happening to, but there haven't been any reports of it yet...

"This is so complicated... My lower abdomen does ache a little, but... come on, there's no way I'm really going to change..."

Why did I ever sell my game console? Passing the time with only my phone was starting to get difficult.

Dinner had quite a bit of meat and was tasty.

As it got past nine and bedtime drew near, I began to feel afraid of going to sleep.

What if I really did change? The nurses had installed a camera to record my physical changes.

Of course, I could have refused, but if I really changed, proving I was still myself might be difficult.

So I simply agreed. They said they would only record me while I slept tonight, not every day, so what could go wrong?

The morning sunlight woke me.

When I opened my eyes and raised my arm, I saw an arm that wasn't my own.

It looked subtly... thinner and whiter.

"Ah, ah."

My voice too? What's going on? This makes no sense. Is this even possible?

My voice was different, too...? When I stood up, my weight shifted forward.

"Huh...? Breasts...? What is this...?"

Wow, breasts. Looking down from my own perspective, I couldn't see my lower body at all.

But I'm Korean—could Korean genes really produce breasts this size?

No, I had gained some weight from being lazy and never exercising, but could changing sex alone really give me a figure like this?

"Wow... I got slimmer... How amazing."

When I touched my stomach, it was much slimmer than before. Had all the fat gone to my breasts...?

"Ugh, the bathroom..."

I still had to use the bathroom. I couldn't hold it in, after all. Yeah.

I was absolutely not going because I was curious whether even my genitals had changed. Absolutely not.

I stood in front of the toilet and took off my pants. It was smooth; that familiar sensation was gone.

"Huh...? It really changed...? Sob, I'd never even gotten to use it, and now it's gone?"

Standing up to pee was no longer possible. Since I was a girl now, I had to sit down all the way.

Well, even when I was a man, I often sat down because standing caused everything to splash around, so the position wasn't awkward. Still, it felt strange to have something that had been there disappear.

But these breasts are way too big, aren't they? I can't see anything below them... This is the kind of size I'd only ever seen in manga, right in front of me...

A lot of my body hair had fallen out too... Naturally, there wasn't a beard in sight when I looked closely in the mirror.

I hadn't grown much facial hair to begin with, but I'd never been this smooth...

"Wow... That's amazing. Other than my head hair and eyebrows, I can't see any hair at all... Is most of it just peach fuzz...?"

It was sad that I'd suddenly changed, but it was also fascinating to see my body like this. I'd always worn long pants because my legs were so hairy, but with these smooth, pretty legs, could I pull off dolphin shorts too??

It would soon be time for breakfast, but I should tell them about this change right away...

Thinking that, I pressed the call button, and a nurse came a few minutes later.

"Wow... She's pretty... Gasp! S-Sorry."

"Ah, no, it's okay..."

If I'd startled the nurse that much, then fortunately my appearance must have changed for the better.

The nurse adjusted the camera and said,

"I'll report to the doctor right away, quickly check the footage recorded by the camera, and come back~ Enjoy your breakfast."

"Yes, thank you~"

Wow, my voice was completely a girl's voice... Even producing such a high pitch on purpose would've been difficult before, but now it came out naturally...

Knock, knock. I heard a knock, and the hospital room door opened.

"Uh... this is Jihoon's room, right?"

"Ah, yes. I'm Han Jihoon."

"Ah, so you're the patient with that rare disease. I can't believe a disease like this really exists."

"Haha, I guess so..."

"Enjoy your meal!"

"Yes, thank you."

The employee who brought my meal quietly muttered about how pretty I was and how fucking jealous they were, then left the room.

I did look pretty in the mirror too, but was I really that pretty...? Would the doctor who came later space out when he saw me too...? Haha...

Wow, even looking at them again, my breasts were fucking huge...

"Ah, enough touching them. Let's eat..."

How was I supposed to explain this to my family or friends? My appearance had changed quite a bit, making me look younger too. It would be a relief if at least my fingerprints were still the same...

As I fiddled with my phone, wondering who to contact, I decided to eat first and think about it afterward.
