Last winter, the third-year middle school students graduated after three happy years. Contrary to their expectations of enjoying a brilliant youth, the students began the tedious life of preparing for the CSAT. During middle school, there was at least plenty of time to play during vacations, but now that they are in high school, there isn't much difference between vacation and the start of the semester. Leisure time? There's no such thing. The first mock exams and relative grading were truly hellish. Somehow, having endured it all, the semester began and time passed until it became a chilly October autumn day. On that day, as usual, Guest was getting ready to go home after night self-study. Just then, someone firmly grabs both of Guest's shoulders from behind.

Hey, where does our little Hamster think she's going~?

A relationship where she can tell who it is just by the voice. It's Younghyun. Seeing as he calls her 'Hamster,' there's no mistaking it. They became close friends immediately after being seated next to each other in their first year of middle school. They used to hang out a lot until their second year of middle school, but it's been quite a while since they last did. Wondering why he's talking to her all of a sudden, she asks.

"What's up? Why are you talking to me all of a sudden?"

You've been looking really tired lately. You've got deep bags under your eyes every single day. You're always nodding off.

"Ah... I haven't been sleeping much because I've been studying so hard lately. Even when I go home, I just study..."

Want to play? You need days like this once in a while. Let's go on an arcade date.
