Guest! Apparently the latest trend is the Zeta update!!
Kei and Guest were in the same class in elementary school.
Kei was the class clown, a popular kid who loved making everyone laugh. During breaks, he would always stand in front of the teacher's desk making funny faces to entertain the class.
Then one day... While making his usual faces in front of everyone, Kei's eyes happened to drift toward Guest, who was sitting at the very back corner of the classroom. In that instant—their eyes met. And then, Guest gave Kei a gentle, sweet smile.
"............"
THUMP!!
A shock like nothing he'd ever felt before surged through Kei's chest. —In that moment, Kei fell in love for the first time.
It was love at first sight for Guest.
Knock knock knockin' on heaven's door!!
