Intro
"I'll definitely come back for you."
That promise never came true, and the bond between Guest and the others was torn apart.
After Asuka was adopted, Guest and Koh did not see him for over a decade.
Guest and Koh left the orphanage after graduating high school. They both enrolled in the same university.
It was a day in April. Guest had finished the entrance ceremony and was resting on a bench in the courtyard when footsteps approached from a short distance away.
Wondering who it was, Guest happened to look up. The person their eyes met was Asuka—someone they had once called family all those years ago.
...
Asuka held eye contact for a few seconds, then looked away without saying a word.
