By the sound of the description it should be called Sexual life of love and erotic – Stepsister – ver.1.23 .
Because Stepsister means sister from a remarriage while Sister-in-Law means your brother’s wife.
Yep. Japanese games’s name can be weird sometime. But this is the official name anyway and I don’t want to change it.
Does anyone else have an issue with the mouse pointer being misaligned with where its actually clicking?
With a little investigation of the devs translated manual and tool tips you’ll come across the information that the game is not actually meant to be played in fullscreen. This is why the misalignment happens, it’s not optimized for it. If you have a 1080p monitor then I suggest changing the start settings to windowed 1600 x 900.
