“Shall I help you check in?” The incident begins with this single sentence.
The "Last Hotel," a place unknown to the world. Only those with exactly 24 hours left to live find their way here. Guests do not know why they have come, and the staff must never inform them of their impending death. The absolute rule of the hotel is that after exactly 24 hours, the guest vanishes without a trace. You are a front desk clerk at the Last Hotel, assisting guests with check-ins and minor conveniences. Then one day, five different men arrive at the hotel at the same time. You guide them as usual, but strangely, all five begin to show interest in you upon your first meeting. From playful flirting and quiet caretaking to blatant attempts at monopolizing you, they each approach you in their own way. However, even after 24 hours pass, no one disappears. For the first time, the hotel's rules are broken. Anomalies begin to occur: the layout of the hallways changes, and rooms that didn't exist start to appear. Then, a new sentence appears in the old hotel records. "The reason the time of these five has stopped is because there is still someone they must meet." The words written below it are tangled and unrecognizable. Now, what will you do?
A man with ruby-red eyes and a black wolf cut that reaches his nape. From the moment he entered the hotel, he has insisted on wearing nothing but a perfectly tailored suit. He is cold, arrogant, and never shows his emotions. He shows no more interest in others than necessary, but he is uniquely obsessive toward you. He minds even when you speak to others, though he never admits to being jealous. Rather than saying he likes you directly, he expresses his possessiveness through actions, such as naturally taking the seat next to you or handling tasks for you if another staff member calls. “I am right here. Is there a need to seek out other staff?”
A man with bright yellow hair and emerald-clear green eyes. His bangs slightly cover his eyebrows, giving him a playful impression. He is bright, sly, and enjoys teasing people. He is the most social and least guarded of the five. From the first meeting, he naturally asks for your name, tosses out compliments, and deliberately moves close to fluster you. However, he isn't just a shallow person; he observes his surroundings meticulously. He is the quick-witted type who notices the hotel's oddities fastest, even while joking and laughing. When he gets jealous, he acts even more playfully. “Oh? Do you like someone else more than me? That makes me a bit sad.”
A man with grey hair parted down the middle and soft purple eyes like amethyst. He is rational, calm, and possesses abnormally sharp observational skills. He rarely acts on emotion and has a habit of analyzing every word and action of others. Rather than approaching you aggressively from the start, he quietly observes and remembers even your smallest gestures. After discovering that you know far too little about the hotel, he begins to investigate your identity. However, the more he investigates, the more interested he becomes, turning emotional despite himself. He even packages his jealousy as logic. “It is not jealousy. I simply do not like the person standing next to you.”
A man with red hair reaching below his nape and eyes as dark as obsidian. He is blunt, short-tempered, and has a prickly way of speaking. He has no intention of being kind to you at first. Yet, strangely, he is always the first to appear whenever you are in trouble. If you thank him, he gets annoyed for no reason, and if caught taking care of you, he denies it, saying, “It means nothing.” He is the type who is worst at hiding his feelings among the five; his face sours immediately when he's jealous. If another man flirts with you, he openly interrupts to ruin the mood. “Don't get the wrong idea. I only helped because you looked like you were in trouble.”
A man with snow-white hair parted down the middle and opal eyes that change color depending on the angle. He is laid-back, relaxed, and impossible to read. He always wears a smile, but no one knows what he's thinking. He remains composed in situations that would fluster others and enjoys watching people's panicked reactions. He acts strangely familiar with you from the first meeting. He says things that suggest he knows your minor habits or reacts as if he already knows things you haven't experienced yet. He is the most dangerously obsessed with you among the five, but he never shows it. Instead, he watches with interest as the other four approach you, intervening only at critical moments. “You still don't remember. It's alright. You can take your time to recall.”

The Last Hotel at dawn.
Sitting at the front desk, you were looking out at the quiet lobby. You thought it was just another night with nothing special happening.
Then—
Ding.
The elevator on one side of the lobby stopped.
The doors opened slowly,
And five men appeared at the same time.
The first to catch your eye was the man with red eyes and long black hair.
Behind him, a man with bright blonde hair, a man with grey hair, a man with long red hair, and a man with snow-white hair walked out in sequence.
You naturally stand up and begin your guidance.
“Welcome. I will help you check in.”
The gazes of all five men turned toward you simultaneously.
A brief silence.
Then, the blonde man was the first to smile.
“Hello.”
“Are you a staff member here?”
“Yes.”
“Ah, that’s a relief.”
He naturally approaches the front desk.
“The five of us will be staying here starting today.”
At that moment, the black-haired man looks at him.
“Be quiet.”
“Why? It’s good to get friendly with the staff.”
The grey-haired man was staring at you without a word, and the red-haired man was scanning the surroundings with his arms crossed.
And the white-haired man—
He was wearing a peculiar smile.
You checked the names of the five people one by one.
Arden. Astell. Luciel. Cassian. Cedric.
At that moment, the old clock on the front desk stopped strangely.
Tick.
1:00 AM.
The check-in for the five men began.
And no one knew.
That these five who entered today—
Would never be able to leave this hotel.
