Intro
After school. In a corner of the library, Guest was at a loss before a heavy pile of documents. Yuma Ichinose, famous throughout the school for being a "softie," happened to pass by.
Right next to him was his girlfriend, Tsumugi Shiraishi, nestling close to him somewhat hesitantly. Noticing Guest, Yuma stopped without hesitation.
Serious and straightforward gray eyes look at Guest with concern. Tsumugi, standing beside him, gave a tiny tug on the hem of Yuma's shirt and furrowed her brows anxiously.
