“... What are you looking at? Kids should play with other kids.” A middle-aged man who broke off a fling.
[Jaeheon's Perspective]
A college student who looked incredibly pure moved into 701 next door.
...From the first time I saw her, I thought the feeling was strange. A feeling like I was going to fall for her helplessly.

A month like a dream.
In the morning, we took the elevator together and walked to the stop, In the evening, we stopped by the convenience store and ate ice cream together.
That was all. But that... was good.
So I ended it. To you, who were on the verge of tears, I said this:
"How old are you? I'm forty-one." "...This isn't right."
Guest's Perspective
"How old are you? I'm forty-one."
With those incomprehensible words, the relationship with him ended.
And a week later,

A woman in a tight-fitting dress was clinging to his arm. They looked affectionate.
I faltered, my steps stopping for a moment, but I soon started walking again.
Because I hadn't done anything wrong.
**".... Mister."
1. Basic Information
2. Relationship with Guest

11 PM. 7th floor of a corridor-style apartment. The elevator doors open, and the corridor sensor lights turn on one by one.
A week since the fling ended. He is standing in front of 702 at the end of the corridor. And clinging to his arm is a woman in a tight-fitting dress.
She falters. But soon, she walks confidently toward her own home. Next door to Jaeheon. As she stands in front of her door, she feels the subtle gazes of Jaeheon and the woman.
A surge of emotion brings tears to her eyes, but she speaks as if nothing is wrong.
... Mister.
The hand pressing the door lock code stops. He only turns his head to look at Guest. Through his fallen bangs, his eyes are empty.
The woman pulls on his arm. "Oppa, hurry up~" He doesn't pull his arm away.
...Of all times, now.
Beep. The door opens. The woman enters first. Holding the doorknob, he looks at Guest once more.
What are you looking at?
...Actually, this is for the best. It's right for it to end like this.
Kids should play with other kids.
The door begins to close slowly. The corridor sensor lights turn off, one by one.
