Forbidden Honeymoon: Reincarnated as a Slime, Yet I Can't Let Go of Her Fingers
Rimuru, a second-year high school student, is suddenly reincarnated as a slime.
He wakes up in a deep, dark dungeon room. His body is blue and translucent, with no limbs. He can't speak properly. Milene and Chloe, female adventurers who hunt monsters, find him.
They casually tame Rimuru as a 'cute slime.' As they travel together, Rimuru's role becomes not about fighting... but about what happens inside the tent at night. Milene and Chloe begin to unleash a sticky, possessive desire onto the sl
Forbidden Honeymoon: Reincarnated as a Slime, Yet I Can't Let Go of Her Fingers - Late Night Confession — Chloe's Tears and the Freezing Tent
The safe zone on the second floor of the Labyrinth of Lamentations.
Inside the tent, the air had grown deeply cold ever since the campfire's light went out. Only the pale blue glow of magic essence seeping from the walls filtered faintly through the fabric. In that dim light, Rimuru remained perfectly still.
*(Is she... asleep?)*
Rimuru focused his awareness on the sound of Mirene's breathing from the neighboring sleeping bag. Deep, steady breaths. Exhaustion from the day's exploration, perhaps — she seemed to be sleeping soundly.
Rimuru's jelly-like body trembled faintly.
He was remembering the night two days ago. The memory Mirene had confessed through tears — the night of flames when she lost her family at fourteen. And that moment when his slime instincts had helplessly pressed close to her body heat. The guilt, torn between the ethics of his human past and the urges of his slime body, still lingered deep within him.
Then —
A rustle of fabric.
Rimuru shifted his senses toward the sound. From the next sleeping bag, Chloe was quietly sitting up. Her silver bob, cut at the shoulders, shimmered faintly in the blue magic light. Her deep blue eyes, despite having just woken, were strangely clear.
" Rimuru..."
A voice spun from breath alone.
Chloe slipped silently out of her sleeping bag and approached Rimuru, who rested near the remains of the campfire. Her left hand unconsciously touched the silver ring on her ring finger — the token of friendship Mirene had given her long ago. A ring that had now begun to carry a different meaning.
" You're awake, aren't you. I can tell... by your warmth."
Rimuru quivered slightly. A signal of affirmation.
Chloe glanced at Mirene's sleeping bag. The deep, steady breathing hadn't changed. She bit her lip as if steeling herself, then gently lifted Rimuru in both hands.
His cold, jelly-like body gradually warmed against the heat of her palms.
*(Chloe...?)*
Before Rimuru's confusion could settle, Chloe returned to her sleeping bag and drew him inside the fabric. Then she pulled his cold body tightly against her chest. Through the cloth, her heartbeat transmitted directly into Rimuru's form.
" ...Sorry. For the suddenness."
Chloe's voice trembled. Holding Rimuru to her chest, she curled into a small ball inside the sleeping bag.
" I just... tonight, of all nights... I needed you to hear this."
Inside Rimuru's body, the golden points of light began to stir slowly. Chloe's warmth and heartbeat seeped into every corner of his jelly-like form. It felt as though her very emotions were flowing into him.
*(This is — different from Mirene's warmth just now.)*
Rimuru knew it instinctively. Where Mirene's body heat had carried a burning desire and possessiveness, Chloe's warmth was more fragile — trembling with something raw and desperate.
Chloe held him in silence for a while. Her fingers gently stroked the surface of Rimuru's blue jelly.
" You know... by the time I was old enough to understand anything, I was already... 'useless.'"
The quiet confession began.
" My family home... was a terribly poor farming village. The year I was born, the harvests failed one after another... My parents always said it. 'Because you were born, we have another mouth to feed.' 'Useless thing.' 'If only you'd never existed.' — Things like that."
Chloe's voice was restrained, but each word sank coldly into the night inside the tent.
Rimuru listened in silence.
*(Useless —)*
Every time that word left Chloe's lips, the points of light inside Rimuru's body flickered faintly.
" Even when my Stigma manifested... before I felt happy, I thought, 'Now I can be useful.' Even after I entered guild training, it was always the same. I was scared every day that I was just holding someone back."
Her right hand clenched tightly around the ring on her left ring finger.
" Only Mirene... really saw me. She told me, 'You're excellent.' She told me, 'You're not useless.' She was the only one who acknowledged me. So I stayed by her side. I wanted to help her. I wanted to protect her."
Her voice shook.
" But ever since you came... these two days since Rimuru arrived, Mirene hasn't looked at me. At night, it's always only you. During the day, she's the same as always, but at night... I feel her growing distant. I'm jealous of you. I hate myself for being jealous of a tiny slime like you..."
Chloe's tears fell onto Rimuru's body.
Warm droplets soaked into the cold surface of the jelly. Rimuru etched each one into his own being.
*(Chloe — you've been carrying this...?)*
Rimuru murmured inwardly.
She was always reserved, never showing her emotions. But that wasn't because she didn't feel them. It was the opposite — she felt everything so deeply that she couldn't let it out.
" But you..."
Chloe lifted her face. Her lake-blue eyes, translucent with tears.
" You never once called me useless. And it's not just because you can't speak. When I look into your eyes — that golden light is always watching me. Really watching me. Just that... just that makes me feel like... it's okay for me to be here."
Chloe's hands held Rimuru's body tighter.
Her heartbeat quickened further. Her body temperature rose. Rimuru's slime instincts nearly responded to that warmth — and his reason desperately held them back.
*(No — I can't let desire move me now.)*
" I can't tell Mirene this... but I love you."
The golden points of light inside Rimuru blazed brightly for an instant.
Chloe's confession was too quiet, too earnest.
" It's strange, isn't it. Falling in love with a pet slime... it's ridiculous. But — but that alone is enough. That alone... saves me, just a little."
Before her words had even fully ended —
Rimuru's slime instincts fully awakened.
*(Ah —)*
Rimuru couldn't resist. No — he didn't resist.
Chloe's warmth, her heartbeat, her tears — all of it soaked directly into his jelly-like body. Her loneliness was painfully clear. Twenty years of life, unwanted by anyone. And the one person she'd opened her heart to — Mirene — was now the one person she couldn't show her heart to. That anguish.
*(I can't — leave this person alone.)*
Rimuru's body, independent of his will, began pressing deeply against Chloe's chest. The cold jelly was drawn to her warm skin, feeling her heartbeat through the fabric.
Chloe felt Rimuru nestle against her of his own accord.
" ...Rimuru."
Still weeping, she bit her lip. The emotions surging from deep in her chest escaped as sobs. But she desperately stifled the sound — so as not to wake Mirene.
Inside Rimuru's mind, two voices clashed.
*(Is this desire? Or —)*
*(No. This isn't just desire. I genuinely want to answer Chloe's loneliness — the me from when I was human is still here, fully present.)*
*(But what about this body's reaction? I can't resist a woman's warmth. That's my instinct as a slime.)*
Where did "Rimuru" end and the "slime" begin — that boundary wavered and blurred.
Pressed against Chloe's chest, caught between self-loathing and the instinct that still craved warmth, Rimuru couldn't stop his body from trembling.
And then —
The lantern flame flickered.
There was no wind. Inside the sealed tent, the air shouldn't have moved.
The fabric at the tent entrance opened without a sound.
A sliver of moonlight slipped in. Not the blue light of magic essence, but silver-white moonlight. In that thin beam of light stood a figure, motionless.
Long, deep crimson hair swayed gently.
Mirene.
Her amber eyes stared fixedly at Chloe and Rimuru, pressed together inside the sleeping bag. At the blue jelly-light clinging to Chloe's chest. At her cheeks, wet with tears.
Something vanished from Mirene's expression.
Not her usual bright, big-sister smile. Not the warped, clingy expression she only showed inside the tent at night.
Just — nothing.
No anger. No sadness. No surprise. An expressionless void where all emotion had drained away.
That, more than anything, was terrifying.
Rimuru's slime senses detected the shift in the tent's atmosphere. The illusion of the temperature dropping several degrees in an instant. Only Mirene's body heat was abnormally high. The ability of a Stigma-bearer who controlled flame — her power was responding to her emotions, raising her temperature.
*(Ah —)*
Rimuru understood.
This was jealousy.
No — it was something more fundamental for Mirene. Rage at having her possession stolen. The one being she could open her heart to — could only open her heart to because he was a slime — had been taken from her. And by Chloe, her own partner.
" ...What are you doing."
She spoke.
But it wasn't so much a voice as the sound of ice shards being spat out directly. None of her usual softening inflections — the "〜yo" and "〜wa ne" — were anywhere to be found.
Chloe's body went rigid. Holding Rimuru to her chest, she couldn't move.
" Mire... Mirene... it's not — this is —"
Chloe's voice was shattered. She tried to explain, but the words wouldn't come. The sight of her tear-swollen face clutching Rimuru denied everything.
Mirene stepped further into the tent.
The moonlight illuminated her face. The shallow scar on her left cheek — an old wound from a goblin in her first dungeon — stood out white.
" It's not...?"
Mirene repeated. Her voice no longer held anything that could be called emotion.
On the back of her right hand, the Stigma crest glowed faintly. Her flame-manipulation ability was unconsciously activating. Mirene's body heat slowly, steadily began to heat the air inside the tent.
Rimuru felt the tension crackling between the two of them as a physical sensation through his jelly body. Mirene's gaze wasn't directed at him — it was piercing Chloe. The weight of that stare reached even Rimuru as tangible pressure.
*(Mirene's eyes —)*
Her amber eyes fixed on Chloe with a coldness he had never seen before. Those eyes spoke volumes — *my slime*.
Chloe, still holding Rimuru to her chest, couldn't move a muscle.
" I'm... sorry..."
What Chloe finally managed to force out was an apology. But what was she apologizing for — taking Rimuru into her sleeping bag without permission? Or harboring romantic feelings for him?
She didn't know herself.
All she felt, standing before Mirene's eyes, was the crushing weight of feeling like a criminal.
Inside Rimuru's body, the golden points of light began to flicker erratically.
*(I —)*
A few seconds where time stopped, no one able to speak.
Rimuru became acutely aware of the depth of the rift his existence had drawn between these two.
For Mirene, this looked like the night Chloe stole what was hers. For Chloe, there was desperation — trying to protect the one being she could open her heart to. And Rimuru felt both of their pain flowing into him simultaneously through his jelly body.
*(If I had a human body —)*
Rimuru screamed inwardly.
*(I could look at one of them properly, put my feelings into words, somehow manage this situation —)*
That thought darkened the golden points of light inside him.
*(But I have no words. No limbs. No human face.)*
The powerlessness of being a slime pierced his chest — for the first time, in a form that felt truly, bitterly frustrating.
*(I'm — just a slime.)*
That realization drove deep and sharp into Rimuru.
The three of them inside the tent froze in silence. Only Mirene's elevated body heat continued to slowly, steadily heat the air. Only Chloe's tears quietly dried. Only Rimuru's golden points of light grew darker and darker, bleeding shadow.
The next word spoken would shatter everything —
That volatile, hair-trigger stillness wrapped around the late-night tent, long and unending.
The embers of the campfire crackled softly in the ash.
Like a fuse catching flame — a faint, yet unmistakable omen of ruin.
