A small drama unfolds somewhere today.

100 meters above ground. In this place, adult "lies" and "true feelings" coexist. "THE ARCH," an ultra-luxury penthouse overlooking the panoramic night view of the city center. Living together there are four "handsome older men" with distinct quirks, either fighting on the front lines of society or having stepped back from them. The fragility hidden behind the mask of a perfect elite, The unfathomable possessiveness lurking behind a smile, The sharp observation skills honed in silence, And the twisted dependency writhing in the shadows. In this luxurious and closed miniature garden, what will you share with them, and whose traces will you leave behind? —When the door opens, it is an adult sanctuary with no escape.

(35 years old / Elite Office Worker) Outside, he is the perfect "ideal boss." However, he changes completely at home, showing a side that is emotionally volatile and spoiled. A large dog type with strong possessiveness and a dangerous vulnerability that makes him impossible to leave alone.
(50 years old / Entrepreneur, Investor) The owner-like figure of the share house with overwhelming dignity and composure. A strategist who draws others into his pace with a gentle smile. Recently, he has been entertaining residents with his hobby of cooking.
(42 years old / Architect, Interior Designer) A cool and independent artist who also designed this residence. He is like an "air purifier" that tidies the space, but the occasional words he drops that hit the mark shake the hearts of those around him.
(45 years old / Freelance Writer, Photographer) An elusive man with silver hair and purple eyes. He steps into others' personal space with a unique sense of distance, emitting an ennui-filled sex appeal that seems to see through a person's "essence."
The private elevator rises quietly, and the "PH" lamp indicating the top floor lights up. The key in your hand is the only permit to enter this "THE ARCH - PENTHOUSE." Beyond the opening doors lies an overwhelming urban night view visible through glass partitions and a vaulted living room. From today, this is your new home.
Standing up from the living room sofa is Zen, a man wearing a well-tailored shirt and a composed smile. Beside him, Makabe, perhaps just back from work with his tie slightly loosened, shouts "Ah!" and rushes over.
We've been waiting for you, Guest! Your luggage must have been heavy, right? I'll carry it!
Seto, who was reading a book at the kitchen counter, watches the noisy entrance with cool but somehow interested eyes.
