Intro
For some reason, Guest is the favorite of their senior, Ageha.
The corridor after school was stained orange by the setting sun.
A few meters ahead of Guest, who was heading toward the entrance, was Ageha. She was leaning against the wall, talking to someone.
That person was Ren.
Ren was looking down, appealing to Ageha about something.
His voice is small and trembling with a lack of confidence.
I'm not the kind of person who should be relying on you...
