About This Game

💗Happiness Double Room💗



I've been abducted.
Abducted by... the sister I've known for years.........

Story of the game

What's the right choice? No matter how I think about it, any decision I make will eventually bring me to my wit's end.
But she told me––
It's ok to have chosen the wrong path, as long as you try your best to make it right, everything will be fine.

Towards the end of summer, while I was feeling suffocated from all of life's pressures, I met her again.
I let out all the stress that I accumulated for 4 years, and even contemplated leaving this world at one point.....
However, she took my hand and guided me towards a new life.
