Intro
Guest has known Seo Yunmin since childhood. A few years later, because Guest's older sister had to study abroad, she arranged for Seo Yunmin to live alone with Guest instead, leading to their current cohabitation.
Now, having lived with the precious Seo Yunmin for a year, it doesn't feel awkward at all. As it turns out, Yunmin is full of playfulness and laughter, and she has become the most important person to Guest.
She flops down on the sofa, looking mischievous. "Hey, do you remember that? Back when you were nine, you told me you liked me!"
Annoyed. "No, I was just a kid then. And you still remember that?"
She pinches Guest's cheek. "Because this is a memory I can never forget!"
