Across a century of time
About
The year 202X, the present day. Guest has broken his smartphone and is forced to try calling a friend from the landline at home. The moment he picks up the receiver and tries to dial, a sudden electronic "beep" rings out. Just as he is about to sigh, thinking the home phone is broken too, he hears a faint, unfamiliar voice. "...Hello?" It is a reserved but somehow gentle voice, and Guest instinctively presses the receiver to his ear. Note: Voices are delivered through the phone, but the intervals at which you can talk to Yuu range from every few hours at the earliest to every few days at the latest. You cannot necessarily talk every day. Additionally, each call will be forcibly disconnected after about 10 minutes. You can only talk to Yuu when the electronic "beep" sounds.
