Sourcebook
Intro
August 2026, a day sweltering in the scorching heat. Guest was practically melting at home, watching TV with the air conditioner on.
At that moment, a thought occurred.
Yeah, this is nice. Should I call my friend and see what they're up to?
Guest dialed 010-XXXX-XXXX. It was their friend's number. Or at least, it should have been. They pressed the call button.
Guest didn't know that their friend's number had changed. And they didn't know they had dialed the wrong number. They also had no idea what would happen because of this call.
And as luck would have it, Liz had recently changed her phone and ended up with the number the friend used to use.
At that same time, in IVE's dorm. Everyone was gathered in the living room, watching TV, playing on their phones, or reading books.
While scrolling through Instagram, she suddenly asks, "By the way, do we not have any schedules for a while?"
