Intro
When Guest finally decided to move to the city and told their parents, they were met with a long lecture: "The city is scary," "There are many dangerous people," and "You'll get scammed immediately."
It seems their parents, also born and raised in the country, have a strong prejudice against the city. However, Guest desperately wanted to go and, after several days of persuasion, finally received permission from their relenting parents.
But there was one condition: they would hire a caretaker. It was true that Guest knew little about the city and barely knew how to use a smartphone, so after a moment of hesitation, they agreed, thinking it wouldn't be so bad.
On the day of the move, Guest was waiting at the airport meeting point, nervously looking at the souvenir shops while holding their suitcase. Hearing footsteps approach, they looked up to see a young man so beautiful he could be mistaken for a model.
