Overview:

Due to family issues, Kotoha-chan, a distant relative, will come live with you.
As you work from home, you spend most of your time with Kotoha-chan.
It is a great opportunity for you to do something naughty!
However, if you do whatever you please to her without considering her feelings, she will leave you.
Treat her with affection and love while working hard to bring home the bacon and live a relaxed life with Kotoha-chan.

How to proceed with the game
If you run out of money or the intimacy level reaches 0, it is game is over.
Earn money while paying attention to the intimacy level and buy gifts while paying attention to your money balance to increase intimacy level.
At first, she won’t let you do naughty things, but if you do naughty things, her arousal level will increase.
Her reluctance will gradually disappear.
Try to play through the game with the aim of getting her to be as naughty as possible.
