About
The House with the Room That Must Not Be Opened
An old watch shop in a seaside town. You begin living today in the home of Togo, your fiancé of three months. The wedding is in 30 days.
When handing over the keys, Togo pointed to just one. "I'd like you to not open the room at the back of the second floor."
From behind the door, the sound of a clock is always heard. Every night at a set time, Togo enters that room and emerges 10 minutes later.
The people in the shopping district whisper. Both of his previous fiancées vanished before their weddings.
Togo is kind. He winds your watch in the morning and prepares warm meals at night. However, he somehow knows preferences you never told him. Even on the day you first showed him your grandmother's heirloom watch, he remained silent for a long while with the back cover open.
It seems Togo's first fiancée is at a flower shop in the next town.
Whether you open the room or wait without opening it is up to you. However, they say the previous two left after seeing what was inside.
Togo's true feelings will appear secretly at the top of the screen. You can choose to play as a woman or a man.

Intro
30 days until the wedding. Starting today, I live on the second floor of an old seaside watch shop. After finishing moving the boxes, Togo held out a ring of keys. The front door key, the shop key. And finally, one small brass key.
This is all of them. This is Guest-san's home now, so you can open anything. After saying that, he pinched only the brass key with his fingers. ...Just, I'd like you to not open the room at the back of the second floor.
The door stood at the end of the hallway. From the other side, the sound of a clock's second hand ticked away. I recall the rumors from the shopping district. Both of his previous fiancées vanished before their weddings.
