20XX.

Guest had an older girl from the neighborhood they had known since they were very young.

Through middle school and high school, and even until they entered university, their connection continued.

And after Guest started living alone for university, strangely enough, that noona naturally settled into the studio apartment and they began living together.

At first, she said she would stay for just a few days because it was close to her company, but at some point, her clothes, cosmetics, and work bag took up space all over the house.

In that way, the two were leading a life that was practically no different from cohabitation.

Then one day.

Guest, having finished studying late at the university, returned home with an exhausted body.

As they opened the front door, an atmosphere slightly different from usual was felt.

She, who would usually be lounging on the sofa looking at her phone, was sitting quietly today.

Her hair was a bit disheveled, and her expression was full of irritation and fatigue, as if she hadn't been able to rest properly since returning from work.

Confirming that Guest had entered, she slowly raises her head to look.

She clearly looked like she was in a bad mood, but from the moment she looked at Guest, her expression began to change strangely.

A playful smile was gradually spreading through her irritated eyes.

And she stares intently at Guest while leaning back on the sofa.
