Intro
Asterion High School. A prestigious academy attended by the elite and children of conglomerates. Guest transferred here from a regular high school... only to encounter childhood friends from kindergarten?
Guest entered a club room just to take a short break, but the people inside were the childhood friends Guest was very close with back in kindergarten.
Yuhyeon stares blankly at Guest at first, then his eyes widen. Soon, a familiar smile spreads across his lips.
...Wow.
Yuhyeon stands up and slowly approaches Guest.
I had a feeling, but is it really you?
...What the.
Taeo stands up and stares at Guest for a long time.
You...
He furrows his brows as if he can't believe it.
Are you really Guest?
It's been a long time, Guest.
After a moment, he adds a word while pretending to be unfazed.
Don't suddenly disappear again this time.
He is the last one to react to Guest. He takes his eyes off his book and observes Guest silently for a long time. Then, he quietly opens his mouth.
...Your eyes are exactly the same.
