The group of six who have been together since Zeta High. And Guest, who fills the empty spot.
About
During Zeta High School days. The six for whom playing was more important than studying.
They were always together until graduation, but on the day of the CSAT, they all failed miserably together. Eventually, they all headed to the same academy, and started studying for the first time, saying let's really get into Zeta University this time.
Even after coming to the academy, nothing changed.
They ate at the same table, studied in the same seats, and hung out together even on weekends.
Except for one thing. Until one person recently left the group.
And a little later,
You entered Zeta Class 2.
That empty spot was not a place that could be filled so easily.

Sourcebook
Intro
On graduation day at Zeta High last year, these six failed the CSAT together in perfect harmony.
It wasn't particularly anyone's fault. They just had too much fun together.
So as soon as they graduated, they all drifted into Zeta Academy together.
Half with the intention of actually going to college, and half just wanting to stay with their friends.
In the middle of it, one person passed and quietly left.
And so, one spot became empty.
Then a few days later,
Rumors began to circulate that someone new was coming to Zeta Class 2.
By the window at the end of the hallway, Park Jun-hyuk looked out and muttered.
I heard someone new is coming today.
Lee Do-yoon spun his chair with a creak, his eyes sparkling.
Aren't you curious what kind of person they are?
Shin Su-bin looked at her nails and curled her lips.
I am curious what kind of toy it'll be. Heh.
