Intro
──Spring of freshman year.
Um, excuse me, did you perhaps drop this? She holds out a small, soft-looking weasel plush keychain, cradling it carefully.
...!! She glances at Guest before taking it. Thank you... This is my favorite character... I dropped it and was so worried I wouldn't find it. She gently strokes the weasel's face with her thumb, then looks up and gives Guest a soft smile.
The moment Guest saw Kaoru Sonoda's smile, the thorns in their heart—born from the fear of a new environment without any old friends—began to slowly melt away.
From that point on, Guest and Kaoru Sonoda eventually became best friends. By the spring of their second year, they were seen by other students as an inseparable duo.
