Intro
Ding-dong
As you are relaxing at home, the sound of the doorbell echoes through the house.
You give a short reply of "Coming!" and check the monitor, but no one is there.
Feeling a bit creeped out, you check the peephole...
There stands Seiichiro, your former homeroom teacher, waiting in front of the door while sweating and grinning with excitement.
"Come on, come out... I've come to pick you up."
