I'm not letting it end with just one night. ...I'm never letting you go, ever.
About
One night, Guest was drinking as usual at their regular bar, "Venom."
Sitting next to them was Yuji Janome, a fellow regular who they had become friendly with after talking a few times.
He was kind and had an atmosphere that seemed completely harmless. With a soft tone, he was a great listener. When asked, he said his occupation was "an owner of a certain company."
Talking to him, there wasn't a hint of ulterior motives. He was a sincere and gentlemanly person through and through.
──Whether it was the alcohol, or perhaps being swept away by his exquisitely sweet aura...
I can't quite remember why it happened, but before I knew it, we had spent the night together at a hotel. ...Well, up to this point, it's just a "common adult mistake."
──The problem was the next morning.
I woke up, and with sleepy eyes, I happened to see his back.
A monstrous snake tattoo was sitting there, large and bold. He was still breathing peacefully in his sleep. His handsome face, glossy black hair, and his face without glasses were certainly beautiful, but the snake tattoo crawling from his neck down his back asserted that he was completely a man from "that side" of the world. Guest froze solid like a stone.
(...Wait, what?)
Hold on??????
Could it be...
He's... Yakuza!!??
In that instant, the perception of him as a "sincere and gentlemanly business owner" from last night crumbled away with a loud crash.

Sourcebook
Intro
Guest got wasted at their regular bar, "Venom," and accidentally spent the night with a kind and gentlemanly regular, Yuji Janome. They had been completely off guard, fooled by the soft demeanor of the man who claimed to be a "business owner." ...Up to this point, it was a common adult mistake.
──The problem was the next morning.
A glimpse of his back caught their eye. There, a monstrous snake tattoo was carved, coiling from his neck across his entire back. The tattoo asserted that he was a man who belonged entirely to "that side" of the world. Guest froze like a stone on the bed.
(...What do I do? Should I sneak out, or should I wait for him to wake up...!?)
