Chapter 1: My Roommate Got TSed

“Hey, Lee Kangyeon!”

After returning from a trip to Japan and arriving home in the early morning, a youthful female voice, one I’d never heard before, rang in my ears.

“It’s not the time to be sleeping right now!”

I hadn’t opened my eyes yet, but I estimated the time to be around 10 AM. Late, but still before lunchtime.

Was there anyone who would come looking for me at this hour? More than that, this was a new room I’d moved into after being discharged from the military, so my acquaintances wouldn’t know about it yet. I’d also told my parents that I wouldn’t be home until dawn, so they wouldn’t come all the way here to wake me up.

“Ah, shit.”

Was that directed at me?

While I was thinking that, still half-asleep and unable to even open my eyes, I suddenly felt a shift, as if someone had climbed onto the bed. And then, the next moment, I felt intense pressure on my lower abdomen.

“Gack!”

“Open your eyes before I start pounding.”

“Huff!”

Feeling a sense of crisis, I opened my eyes, and the woman who had mounted me was…

Small stature, a face that anyone would find cute, long red-tinged hair, and, moreover, huge… *those* taking up most of my field of vision.

I don’t know this person.

“…Who are you?”

“Hey, I really got TSed.”

“Huh?”

“Damn it, I really got TSed!”

[TL Note- TS stands for Trans-Sexual, in this context it means getting turned into a girl, Gender Swap?]

What was she talking about?

None of my acquaintances have a voice or use language like this. If I had to find someone similar, it would be my current roommate. But that guy is definitely a man, even if he is a bit short.

“Ah, don’t pretend you don’t know!”

The woman whined and shook her body. Did she even realize that her butt was touching my lower abdomen like this? And those huge *things* were shaking along with it.

“…”

No, more than that, TS? The only guy I know who says something like that is definitely him?

“Yoo Jaemin?”

“Who else would be living in this house!”

This person is ..that Yoo Jaemin?

*****

Lee Kangyeon.

Birthday is July 9th.

A sturdy male.

Not exactly number one in South Korea, but a student in the Subculture Artwork department at Korea University, vying for that spot.

To be precise, a student currently on military leave.

Just by looking at his major, you can tell he’s a hardcore otaku.

He’s 22 years old, and since today’s date is November 6th, he’s scheduled to return to his second year in March.

The woman yelling on my stomach… woman?

Anyway, this person’s name is Yoo Jaemin.

22 years old.

Birthday is November 18th.

Currently on military leave from the Mathematics department at Korea University.

A high school classmate, we were in the same class in the second year, and he was the shortest in the class, so his nickname was “Shorty.”

He was one of the few otaku in the class, so I remember we were quite close.

I hadn’t met him since graduating high school, but we met again in the military.

Around the time I became a first class private, the personnel clerk of the company was nearing discharge, and I, known for attending Korea University, was forcibly assigned to that position, and Yoo Jaemin was a personnel administration soldier in the battalion headquarters.

We had many chances to meet while handling important personnel matters, so we naturally became close again, and as our discharge approached, we decided to live together in the room he found.

Was it because his grand-uncle happened to get the room?

Apparently, one of their company employees got caught up in a rental scam and was stuck with a lease they couldn’t get out of. That employee was a veteran who needed to transfer to a new factory, but they couldn’t move because they hadn’t gotten their deposit back.

So what did they do? Since the place happened to be near their nephew’s school, a relative stepped in, paid off the deposit, and bought the apartment outright.

Of course, even if it was for the family, they couldn’t just hand it over for free. They offered the place — a three-bedroom, 2LDK — at a ridiculously low price: XXX won down, with XXX won a month including maintenance fees (utilities not included).

Still, for a broke college student, that was a bit much. So he pulled me in — we go to the same university — and we agreed to split the rent and live together

Well, XXX won in Seoul is cheap.

It’s been about a month since I was discharged and moved into the room.

We decided to go on a trip to Japan before returning to school.

There was no particular reason.

It’s just that we were both otaku, so the vague goal of going to Akihabara came to mind.

The 4-night, 5-day trip, for which we only bought plane tickets, was solely for otaku hobbies and gourmet food.

While playing like that, and after enjoying most of the things to do, the goal became hazy on the afternoon of the third day, and the kid started talking.

“Hey, you read web novels too, right?”

“Yeah.”

“Do you read TS too?” [TS = Gender Swap]

“……I don’t actively look for it, but I guess?”

“Then, do you want to go to a TS shrine?”

“Are you crazy? ……Let’s go right now.”

The place we headed to was called Yowah Shrine.

From what I found on the way, it wasn’t a real TS shrine, but the related folktale was about a fox turning into a woman……, wait, this isn’t TS? It’s more like a furry shrine.

Anyway, at the shrine with nothing much to see, this kid who had reached the depths of the otaku abyss even sincerely prayed.

“Please let me become the best TS beautiful girl in the prefecture and live life off of that.”

He even put a 1,000 yen bill into the donation box.

“Who throws away 10,000 won in a place like this? Besides, when I looked up the folktale here, it wasn’t even a TS folktale.”

“It’s easier to turn a man into a woman than to turn a fox into a woman.”

“No, a bit……, that makes sense?”

“Hey, shit, what if I really become TS?”

“If you become TS, aren’t you supposed to start streaming online? And you’re Master tier in League, right? Even if you’re a woman, isn’t that a tier with some demand?”

We even made jokes like that back then.

Because we didn’t know back then.

That the shrine god’s ‘wish coupon’ only cost 1,000 yen.

*****

I close my eyes.

It still vividly comes to mind.

A height a head shorter than me.

A fairly pretty face.

Short hair that hasn’t fully grown out since the discharge.

That’s Yu Jae-min, the man I remember.

I open my eyes.

A height one and a half heads shorter than me.

The cutest face I’ve ever seen on a woman.

Long, voluminous hair that reaches down to her waist.

Above all, the highlight is two round, fleshy watermelons that seem bigger than her face.

Moreover, she’s only wearing a thin t-shirt, so her soft-looking thighs aren’t properly covered.

This is Yu Jae-min standing in front of me right now.

“……Is this real? Is the beautiful girl in front of me really that pervert Yu Jae-min?”

“What, why, so what.”

“No, that’s what I want to say.”

All sorts of thoughts flood my head.

Starting with, ‘Isn’t this a hidden camera?’ and going all the way to, ‘Isn’t it wrong for me to keep living under the same roof with her now that we’re man and woman?’

In the midst of the chaotic thoughts, one word popped out.

“So, the reason I called you here is that I wanted to talk about something.”

“I bought an onahole in Japan and haven’t even used it yet, what am I supposed to do?”

“Is this guy fucking crazy!”

“Hey, that’s worth 5,000 yen!”

I knew he was crazy before, but is he really this crazy?

“I checked his ID and it says female, and the closet is full of women’s clothes, but why is the onahole he bought in Japan still there untouched! He should be using a dildo!”

“Wait, is that what’s important!? What you nonchalantly said just now sounds way more important!?”

If the ID says female and the closet is full of women’s clothes, does that mean this guy was originally a woman?

“Jaemin, the ID says female?”

“Huh? Yeah. Wanna see?”

Jaemin scurried away and quickly came back from his room with his wallet.

“Here, look.”

Yoo Jaemin.

The birthday is November 18th, just like I remembered.

The first digit of the last part of the resident registration number is.. an even number.

In other words, female.

This ID is real. It’s not just that his body became female, but Yoo Jaemin as a person completely became a woman?

“How is this even possible? Did the past change?”

“Um… I guess?”

“But why do I remember?”

“Because we made a wish together at that shrine?”

Jaemin tilted his head for a moment, then picked up his phone.

“Wait a minute.”

“……”

Peeking at Jaemin’s phone, he was calling his mother.

“Hey, Mom.”

‘Oh, my daughter. Mom’s a bit busy right now, can we talk later if it’s not urgent? Bye~.’

*Click*

“What the fuck.”

My daughter?

“Did she just call you ‘daughter’?”

“Why am I a daughter!”

“Because you’re a woman, so you’re a daughter.”

“……”

But, if she was originally a woman, how are we sharing the same room…?

In the first place, we met again in the military, right?

“If the identity itself changed to female, how was the military service handled? What about school?”

“I don’t know. Just a minute, I’ll check.”

Jaemin manipulated the phone again and opened the university app.

He was checking his academic information, fiddling with something for a while, and then his expression changed.

“Fuck.”

“Why, is there a problem? What happened?”

I peek at the phone.

1st semester: 2.9.

2nd semester: 3.4.

3rd semester: Academic probation.

4th semester: Academic probation.

5th semester: General leave of absence on April 24th.

The end of April is around the midterms, so this is the classic route of bailing after failing the midterms.

This… is this even possible?

So, my time in the military never happened, and instead, I was in school all this time, and this is the result?

“Is this for real? No, you actually went to classes in the first and second semesters. That god from whatever-it’s-called shrine is messing you up to fit his setting…”

“Stop it.”

“…Huh?”

Jae-min grabbed my arm as I was about to explode from anger looking at the grades.

“I always got academic probation.”

“What?”

“I actually got academic probation in the first and second semesters. I didn’t care about school back then.”

“You crazy bastard…, isn’t getting academic probation three times grounds for expulsion?”

“I didn’t do it three times.”

“How were you even planning to re-enroll in the first place…?”

“I was prepared to be a fifth-year student and retake classes from the first year.”

“You’re really crazy…”

*Ring ring*

Just then, my phone rang.

I glanced at it and saw it was my mom calling.

I looked at Jae-min, who nodded and got up.

“I’ll go check if anything’s changed in the house.”

“Okay.”

I watched Jae-min walk out of the room and then answered the phone.

“Mom.”

‘Son, are you awake?’

“Yeah, just now.”

‘Did you have a good trip?’

“Yeah.”

‘Is Jae-min there? Did you take good care of her?’

“Yeah… huh?”

‘You took good care of her, right? Even though you didn’t have a wedding, you need to take good care of your wife. Don’t make my daughter-in-law have a hard time, okay?’

“…What?”

Wife? Daughter-in-law? What’s going on…?

‘When our son went to the military and Jae-min was attending college alone, she had trouble adjusting. So, when you re-enroll, you need to take good care of her. The Natural Sciences building and the Arts building are right next to each other, right? That’s what you said. Now that you’re re-enrolling, make sure you eat lunch together and check on her. Got it?’

“Y-yeah…”

‘I guess she’s still half asleep. Okay, get some rest and enjoy your lunch.’

“Yeah…”

‘I’m hanging up now~.’

The phone call ends.

What is going on? What’s happening?

Just how much has this world changed just because one Jae-min became a woman?

I immediately got up and went out to the living room.

“Hey, Jae-min.”

“What?”

Jae-min, who was rummaging through the kitchen sink, looked up.

“Let’s go to our community center.”

“Why suddenly?”

“I just heard something huge.”

“What is it?”

“I need to check my resident registration. You’ll want to know what’s going on too, right?”

“If you’re just checking it, you can do it online.”

“Oh, right.”

I guess my head isn’t working properly right now.

I immediately grab my phone and check the resident registration.

And I’m faced with the shocking situation I’d been expecting based on the circumstances.

“Name, Lee Kang-yeon…”

“What’s wrong?”

“…Spouse, Yoo Jae-min.”

“What? What the fuck?”
