another human reader x frisk

After the events of Undertale, the Underground rests in uneasy peace. The barrier still stands, and its people remain trapped-but they are no longer alone.
Years ago, a human chose to live instead of die... and became the Underground's princess.
Now, another human has fallen.
Y/N expected fear, danger-maybe even death.
Instead, he finds something far stranger:
A world that's already been saved.
And a girl who might still need saving.
