Episode 1: My Fiancée Descends—With Handcuffs in Hand

The birds outside chirped cheerfully by the window. Warm sunlight streamed into the plush bed, making the room unbearably hot.

That’s when I, Rei Ukaha, finally began to wake up.

“…Ugh, my head hurts. Where the hell am I?”

I had no memory of the previous night. My head, back, and legs all ached, and for some reason, my wrists throbbed too.

Wait a second—last night… I was at a drinking party, wasn’t I?

Staring blankly at the oddly vivid pink ceiling, I tried to piece things together. My arms and legs felt oddly restrained, making it hard to move.

“Huh? Wait… What’s going on here!?”

That’s when it hit me.

I was in a love hotel. And—

“Handcuffs!?”

For some reason, I was handcuffed in nothing but my underwear. To make matters worse, a towel-wrapped chain bound my ankles to the bed frame.

“What the hell is this!?”

Since when did I start indulging in bondage play when I got drunk? My transformation since my university debut knew no bounds.

“…Was I always into this kind of thing?”

They say alcohol reveals your true self, but this was way too much.

“Oh my, you’re awake now, sleepyhead.”

A woman’s voice interrupted my panic. Emerging from the bathroom was a breathtaking beauty clad in nothing but a bathrobe.

Her chestnut-brown hair fell perfectly straight without a single strand out of place. Even through the bathrobe, her impeccable figure was evident. Her long lashes—my personal weakness—added a striking charm to her face.

“Um… could it be that you are… the dominatrix from last night?”

Given the situation, there was no other logical explanation. Did I really… with her?

“Dominatrix? What are you talking about?”

The beauty tilted her head in confusion, looking so effortlessly elegant she could’ve graced the cover of a fashion magazine.

“I’m… hmm…”

She placed a finger to her chin, pondering for a moment, before speaking again.

“I’m your fiancée.”

“…W-What!?”

Fiancée? What kind of nonsense was she talking about? At this point, I’d have been less shocked if she had claimed to be a dominatrix.

“What’s that look on your face? As if you’re thinking, ‘Oh, come on, this has to be a joke! Even being told she’s a sadistic dominatrix would make more sense!’”

“W-Wait, are you psychic? That’s freaky! Or maybe you’re just really good at acting… Hang on a sec, I need to check in with my friends to figure out what happened last night.”

Thankfully, my phone was right by the bed. Time to get some clarity—

“Friends? Other women? Are they other women? Well, too bad for you.”

“Huh? Wait, what the—?”

No matter how many times I entered my passcode, my phone wouldn’t unlock.

“Oh, dear. Did you forget your new password?”

“Wait, how do you know that? I didn’t even set a new password!”

“Of course I know. It’s… my birthday,” she said, looking slightly bashful.

“What!? How do you even—”

“You were so happy about it last night, remember?”

Her slight blush made her look unbelievably adorable. Somehow, my frustration melted away.

“I’m sorry, but could you tell me what it is again? I’ll change it right after this, I promise.”

“…Fine, just this once. It’s February 14th.”

I managed to unlock my phone while awkwardly fumbling with the handcuffs still on my wrists. However…

“Wait, what? Huh? This can’t be right… All my contacts are gone except for one. And my games and social media accounts are completely wiped!”

Not just my carefully gathered list of contacts from university girls—my male friends and even my family’s numbers were completely erased.

“Well, you said I’m the only one you need,” she said, tilting her head innocently.

“Y-Yeah, but deleting my games and male friends too!?”

“If you have male friends, you’ll end up at mixers, won’t you? And if you have games, you’ll ignore me.”

Her cold gaze sent a chill down my spine, but somehow, she still looked beautiful.

“B-But my family—”

“I considered leaving your family’s contact info, but… I want you to rely on me if anything happens.”

Her frosty expression melted into a faint blush. Adorable.

“Anyway, hurry and get dressed. You’ve got class today, don’t you?”

“R-Right. So, um, could you take off these handcuffs now?”

“Oh, I forgot about those. Sorry.”

Without hesitation, she pulled the key from the pocket of her bathrobe.

Seriously? She even brought the handcuff key to the bathroom?

Later, sitting with my friends in the campus cafeteria, I recounted the morning’s events.

“So, what the hell happened last night? You two were at the drinking party too, right?”

One of them, Akira Isaka, scratched his head awkwardly. “Yeah, but we didn’t see much after you left with that senior.”

“Wait, she’s from our club?!”

“Man, she’s gorgeous. I’m jealous.”

“Ugh, if you managed to get her, I could’ve had a shot too.”

Finally, Akira recalled something. “Oh yeah, before you left, I think you said something like… ‘Please date me with marriage in mind!’”

“Oh, God.”

It was all my fault.

Later, the beautiful senior appeared, pulling me away to eat lunch together.

“Why me?” I asked, as we reached a quiet, empty classroom.

“Why you?” she repeated, visibly irritated.

“I’m just… so ordinary. I’m cheerful, sure, but I’m nothing special. Why would someone like you…”

Her expression softened.

“Listen closely, Rei. My name is Shion Saionji. And I’m the woman who has decided to love you for the rest of her life.”

Her words carried no trace of deceit.

Even if her love felt just a little heavy… it was hard to say no to a woman like her.
