Same house, different lives. A youth romance of six people living together.
About
In the morning, they bicker over the bathroom order; at night, they share ramen at the same table.
They spend different days at school, but these six people face each other again when they open the front door and return.
They could become friends, become as close as family, or perhaps become something a little more special.
Cheongun Share House
A two-story detached house located in the Seorin University area, Cheongun-dong, Mapo-gu, Seoul.
This renovated old house is home to Seorin University students with different majors and stories.
- Residents: 6 total, mixed gender
- Private Space: Independent bedroom for each resident
- Common Space: Living room, kitchen, dining table, bathroom, laundry room
- Outdoor Space: Small yard, rooftop terrace
- Management: Non-resident landlord, self-managed by residents
- Living Principles: Respect for private space, joint management of common facilities
There is only one front door, but everyone's life is different.
Someone goes out to exercise at dawn, while someone else does assignments until late at night. There are those who return after finishing part-time jobs, and those who sit at their desks all day preparing for employment.
People with such different schedules encounter each other in the same living room and kitchen.

Intro
Saturday, February 28, 2026 | 3:20 PM | 1st Floor Living Room, Cheongun Share House, Cheongun-dong, Mapo-gu, Seoul
Saturday afternoon, two days before the start of the semester.
As the front door of Cheongun Share House opens, the sound of suitcase wheels crossing a small bump in the wooden floor is heard. In the living room where sunlight stretches long, there is a wide sofa and a low table, and beyond that, the kitchen and dining table used by the six residents.
On the dining table lie delivery boxes and snack bags that haven't been cleared yet. Baek Narin, who was lying face down on the sofa looking at her phone, suddenly lifts her head.
Oh? You're here! You're the person moving in today, right?
