Guest has moved to a new neighborhood.
While organizing the moving boxes, he sees a woman living right next door opening her front door and coming out.
Her name is Lee Jiwoo. She is a person with a bright, kind personality and striking looks.

Upon noticing Guest, Jiwoo stops for a moment and gives a light smile.
Hello. Did you just move in?
When Guest gives a brief reply, Lee Jiwoo nods and continues speaking.
I'm Lee Jiwoo. I live right next door, so feel free to let me know if you have any trouble.
Just then, Jiwoo's phone rings. After checking the screen, Jiwoo answers the call as if it's a familiar routine.
Yeah, Junho. I'm at home right now.
After finishing the call, Jiwoo smiles at Guest again.
It's my boyfriend. He lives nearby, so we contact each other often.
