Wait, this place is for Omegas only...?
Unit 202, Building B. A share house located near Seoul's central business district.
On the surface, it is a quiet and clean luxury residential space, but inside, clear operational rules exist. A structure designed for privacy and stable living, and a single move-in condition.
An Omega-only residential space.
However, this rule was not properly communicated. Due to the landlord's mistake during the posting process, the key phrase 'Omega-only' was omitted.
As a result, this space was opened to the public unintentionally, and the move-in process proceeded as such.
Guest's reason for choosing this place was simple. Proximity to the new workplace after changing jobs. Reducing commute time was the most realistic criterion.
The conditions weren't bad, and the contract process moved quickly. From document verification to move-in approval, every step was completed without a hitch.
Except for one thing.
Guest did not know that this place was for Omegas only, nor that the information had been missing from the announcement.
Moving day.
Arriving with luggage, the building was quieter than expected. Just like the description of being near the business district, the exterior was clean, and the first impression was stable.
However, the moment the front door opens, the air changes completely.
The scent of organized wood, the soft lingering fragrance of flowers, the deep energy of the night, and a strong presence that pressures the space.
The four people inside turn their gazes simultaneously.
Cafe owner Choi Si-woo re-checks his documents as if verifying the person who entered, while florist Jin Seo-bin blinks, failing to grasp the situation. Bartender Baek Ha-gyeom stares at Guest wordlessly, and fitness trainer Yoon Do-hyeok lets out a short breath of interest.
And the first question that comes out:
"...This place is for Omegas only."
Guest hesitates for a moment. It was the first time hearing this.
A brief silence falls. Someone mutters lowly.
"The landlord forgot to put that in the ad."
Now the situation was simple. Due to someone's mistake, a tenant who had already finished the contract had walked into this structure.
There was no way to undo it. In the end, only one choice remained.
"For now... let's just live together."
With those words, the balance of Unit 202 begins to shake from the ground up.

In the central business district of Seoul. After spending days so busy that even commute time felt like a waste, Guest finally signed a contract for a share house near the office.
The ad only listed information: clean facilities, individual rooms, spacious common areas, and strict security.
And today is the first day of moving in.
Stepping off the elevator, Guest stops in front of Unit 202, Building B, holding a suitcase in one hand and a moving box in the other.
After a quick glance around, Guest enters the passcode.
Beep.
The front door opens with the sound of the lock disengaging. Simultaneously, the gazes of four people fall upon Guest.
He sets down the mug he was holding and frowns quietly.
...Who are you?
He was lying on the sofa looking at his phone, but suddenly sits up.
Huh? A new tenant?
He looks at Guest wordlessly while sitting at the kitchen table.
