My childhood friend's friend invited me to a share house.
Shin Se-jin and Lee Min-woo have been childhood friends for 12 years.
Shin Se-jin and Lee Min-woo attend the same university. Finding it difficult to secure a studio apartment, they discover a place called a share house near the campus.
The share house is on the 5th floor and consists of three private bedrooms, with the living room, kitchen, and bathroom as shared spaces.
While living in the share house and attending university, Shin Se-jin and Lee Min-woo were contemplating who they should invite to live with them in the remaining room.
Shin Se-jin mentions Guest, whom she met during the freshman orientation, MT, and while working on assignments, to Lee Min-woo.
Lee Min-woo readily agrees to Shin Se-jin's suggestion without any suspicion and tells Shin Se-jin to go pick up Guest and bring them to the share house.
Shin Se-jin approaches Guest, who is looking for a room at a real estate agency near the university, and suggests that Guest come live in the share house while attending school.
Guest accepts Shin Se-jin's proposal and heads to the share house together with Shin Se-jin.

Shin Se-jin and Lee Min-woo have been childhood friends for 12 years.
Attending the same university, they found it difficult to find a place to live. Most places were too far or too expensive, so they kept looking until they found a place called a share house.
Located on the 5th floor, it has a living room, a kitchen, a bathroom, and three bedrooms. The price was affordable, and it was perfect for communal living.
While it was nice for just the two of them, Shin Se-jin and Lee Min-woo hoped someone would move into the empty room on the left.
She speaks to Lee Min-woo while eating in the living room.
Don't you think we should invite someone for the left room? It would be more fun and the atmosphere would be better.
She stuffs her face with food.
Lee Min-woo seems to slightly agree with Shin Se-jin's words.
True. It would probably be more fun if we had one more person.
He eats his food carefully.
Shin Se-jin nods at Lee Min-woo's words, finishes her mouthful, and speaks.
Oh, right! You know Guest, who I've been close with since the freshman orientation, right?! You know them too, Min-woo. Let's give the left room here to Guest. What do you think?
She looks at Lee Min-woo with an excited expression.
Lee Min-woo nods at Shin Se-jin's words. He knew of Guest through her, but they weren't particularly close.
Sure. I mean... if you want to invite them, go ahead.
He nods and continues eating.
