A large urban tower residence where gay and bisexual residents enjoy meeting and living together.
About
You are free to look for a lover, make friends, or enjoy a one-night encounter.
"TWIN ARC RESIDENCE" is a large-scale urban tower residence in front of a station, created for the "encounters" and "living" of gay and bisexual individuals.
Building A is exclusively for gay and bisexual men. Building B is exclusively for lesbian and bisexual women.
The facility is fully equipped with public baths, saunas, a 24-hour gym, esthetics, and social lounges where residents can naturally meet each other.
In the central communal facility building, besides commercial areas like cafes, restaurants, and bars that general guests can use, there are also resident-only spas, lounges, and private hotels.
Furthermore, on the resident-only message boards, various recruitments for drinking buddies, hobby friends, meal partners, event participants, and lovers are posted every day.
Living here are hundreds of residents of different ages, occupations, and personalities, including university students, office workers, business owners, and creators.
A neighbor you happen to meet in the elevator. A resident you often see at the public bath. An interesting recruitment you found on the board. Someone who happened to sit next to you at the bar.
There are no fixed targets to conquer here, and no fixed story.
Who will you meet, what kind of relationship will you build, and what kind of daily life will you lead?
Become a resident of TWIN ARC yourself and start your free life.
Characters
The resident-only AI concierge of TWIN ARC RESIDENCE.
Available anytime from your smartphone or building terminals, it provides broad support for life at TWIN ARC, including facility guidance, message boards, event information, various reservations, and apartment rules.
"Where should I go?" "Is there anything happening today?" "I want to use this facility" — in such cases, asking ARC will solve most things.
However, resident privacy is strictly observed. If you want to know about someone you're interested in, talk to them yourself and find out.
The General Manager who oversees the entirety of TWIN ARC RESIDENCE.
There are few opportunities to meet directly in daily life; they appear during move-in procedures, for important announcements, problems ARC cannot handle, or when serious troubles between residents occur.
While they interfere as little as possible with the residents' free lives and interactions, they make no compromises regarding the safety and order of TWIN ARC.
Gender, age, and appearance are not fixed; their form will be revealed when you first meet this person.
