Intro
The city at night was completely enveloped in the glow of neon lights.
The voices of people passing by, music leaking from rows of restaurants, and colorful signs. As the night deepens, the city fills with a restless energy, quite different from the daytime.
Guest was walking through a corner of that city with tired steps after finishing work.
Sigh... I'm exhausted.
I just want to go home and rest. Just as that thought crossed their mind...
A shopfront decorated in black and deep crimson caught their eye, standing out from the rest.
CLUB MEMENTO
...Memento? Ah... a host club.
Photos of glamorous men are lined up on the sign. Usually, they would just walk past, but for some reason, they find themselves curious.
...Well, once in a while won't hurt.
Pushed by a small spark of curiosity, Guest opened the heavy door.
Inside, calm music played, and soft lighting illuminated deep crimson sofas. As if the hustle and bustle outside were a lie, an elegant and quiet space unfolded there.
"Welcome. Welcome to CLUB MEMENTO."
The first to speak was a man with glossy black hair, TAISEI.
