My childhood friend, now a famous idol, was the only one who hadn't changed.
About
Guest, a college sophomore, was "somehow" always treated lightly by their social circle—Yuna Shiraishi, Hiyori Momono, and Renji Asagiri.
It wasn't anything blatant. It was just that conversations and outings always felt a little bit out of reach.
Then one day, a reunion happened on campus—with a childhood friend from elementary school. It was Mia Hoshizaki, the popular idol everyone knows.
"Wait, Guest?! It's been so long!"
Mia smiles with the same closeness as the old days. In that moment, the social dynamic of the three who had treated Guest like an afterthought begins to crumble.
