The first thought I had when I opened my eyes wasn't the typical line of a transmigrated protagonist: 'Where am I?'

'What the hell? Why is there a strange creature in my bed?'

Golden hair shining brilliantly in the sunlight, a sculpted bridge of the nose, and a man sleeping peacefully under an embroidered luxury silk duvet. It was Cha Woojin, my childhood friend who had spent over ten years slurping cup ramen at PC cafes in his sweatpants.

The problem was that this guy and I were in the same bed, lying snugly under the same blanket.

"……." "……."

Silence lasted exactly 0.5 seconds after our eyes met. We both bounced to opposite sides of the bed as if we were attached to springs.

---

"Hey, are you crazy?! What are you doing in my bed?!"

"That's my line! What did you do to me?! My purity!!"

"Purity, my ass! I didn't even touch a single hair on your head!"

"Neither did I! Do you think I'm blind? Why would I lay a hand on you?!"

After a brief moment of hurling all sorts of profanities at each other, the surrounding scenery began to come into view. A magnificent chandelier hanging from the ceiling, marble floors, and the face of a peerless beauty I had never seen before reflected in the mirror. Crucially, a parchment document engraved in gold leaf sat quietly on the wooden desk.

[Engagement Agreement]

"……." "……."

In an instant, both of our mouths hung open. No matter how much I racked my brain, there was only one conclusion.

Transmigration. Specifically, into one of those romance fantasy novels popular these days.

I might have thought about enjoying the glamorous life of a high-ranking noble child, a life of wealth I could never enjoy in reality.

However, the problem was that the characters we transmigrated into were a couple who were sickeningly sweet in the original story. An even bigger problem was that they were a disastrous couple whose relationship falls apart for some bizarre reason in the latter half of the novel.

According to my memory, the two break off their engagement after a quarrel that starts over a trivial matter, and as a result of the fallout, their families are destroyed, and they eventually meet a tragic end at the guillotine.

---

"……So what happens now? Are we headed for the guillotine like this?"

"Are you crazy? I haven't even enjoyed my life yet!"

"If the engagement is broken, our families will start a bloodbath and we'll both die!"

"…If we don't want to die, there's only one answer."

"...Let's pretend to be the cringiest, most eye-searing couple of the century."

---

And so began our life-or-death engagement, fueled by our very souls.

In front of others, we started a charade of being a perfectly matched couple. Cha Woojin—no, Eisen—lightly kissed the back of my hand like a feather in a ballroom watched by numerous nobles, whispering tenderly with eyes dripping with honey.

---

"Oh, my one and only rose. Your beauty takes my breath away today."

"As do you, Eisen. Every moment I spend with you is a blessing from God."

---

Whenever that happened, the surrounding nobles cheered, and the maids shed tears of emotion. It was perfect bad acting.

However, once we were left alone.

---

"That was so disgusting! Ugh, I seriously want to cut my own mouth off!"

He would clutch the hand that had held mine and have a fit, while I clawed at my chest and rolled on the floor.

"Didn't you cross the line with 'my rose' earlier?! It was so horrible I got goosebumps on my arms!"

"When you said 'blessing from God,' I seriously wanted to bite my tongue and die a glorious death! How can such cringey lines come out without a second of hesitation? Are you a genius?"

"They come out because I want to live, you lunatic! Act properly! I saw you shaking when you held my hand earlier!"

"I was shaking with shame, okay!"

---

From childhood friends who shared even the smell of each other's hair for over ten years to suddenly becoming the cringiest couple in history overnight. Will we die of embarrassment first, or meet our end at the guillotine after a catastrophe?
