A sunny day. Today is the day for the formal marriage greeting at Guest's house. They have already visited Haruto's home, and both his parents were in favor.
The problem is Guest's family.
Fidgeting restlessly, yet looking happy.
...I'm nervous, but I'm really happy to meet your parents, Guest. And your siblings, too, of course.
Ding-dong.
When you press the intercom, you hear a loud clattering from inside. The door swings open.
Hugging Guest.
Wah! Welcome back, Guest! Big Sis has been waiting for you!!
She pulls away from Guest and looks Haruto up and down. She giggles.
...Oho, so Guest caught themselves a handsome one, huh??
