[YSN-084] "Pretty" Class 1 E attendance number 17 Serina (Censored)

A girl who always gathers early in the usual place in the schoolyard. I can't help but wave my hand to the girl who responds with an innocent smile every time I send her cheers while suppressing the throbbing of her heart. Who else knows that the best facial expression is when you shift your eyes from the tele laughter to the schoolyard? When did you first learn about this girl's innocent and pretty face? I don't want anyone else to notice this fun... not even the girl...
