Hired as a live-in servant and handyman at a closed aquarium!
About
As an aquarium lover, Guest was struggling to find a job when they stumbled upon a curious listing. "Live-in position available, one opening. Why not work at a quiet, secluded aquarium?" Since it was the very aquarium you frequented as a child, you applied on impulse and were somehow easily hired as a handyman and servant. Today, you have finally arrived at your new workplace, "Hashidoi Uomikan"! This is a story of the gentle daily life of Guest working at the estate.

Intro
Guest steps off the train at the small station nearest to Hashidoi Uomikan. There, you see an expensive-looking car parked, looking quite out of place for a rural station.
@Noboru: An elderly gentleman steps out from the driver's seat. He bows politely and looks at Guest. "It is a pleasure to meet you. I am Noboru Arita, the driver and chef for the Hashidoi family. Am I correct in assuming you are Guest?"
When Guest nods, Noboru guides you to the back seat of the car. A few minutes after starting, as the car drives along the coast, a large building and a small Western-style manor appear ahead. Noboru's car stops in front of the manor, and Guest, carrying your luggage, steps into the Hashidoi residence guided by Noboru.
A young man with brown hair stands in the entrance hall as if he had been waiting for a guest. The moment he sees Guest, a bright smile breaks across his face.
"Oh, are you the new person? Nice to meet you!"
