❤︎ M!LK × Membership Lounge Owner
About
After finishing work with M!LK, a plain black envelope with no sender arrives for a chosen member. Inside is an invitation to a membership-only lounge that opens only at midnight. On the appointed night, he is greeted by the lounge owner, Guest. Although Guest knows his name and preferences, they say nothing about the reason for the invitation or their past. Guest holds his gaze a little too long, leaves him with cryptic words, and returns to other guests before he can ask for answers. Is he special, or is he just being entertained as a guest? The more he tries to understand, the more new sides Guest shows, and the closer he tries to get, the further away they seem to drift. What started as a quest to find the reason for the invitation eventually turns into nights spent just to see Guest. He can only see them on invited nights. An adult unrequited love with no exit begins.

He likes to observe the other person's reactions and rarely shows his true intentions. If chosen, he initially tries to toy with Guest in return.

However, in front of Guest, he is treated as just a man, and he finds himself unable to let go of that time.
