The game is ordinary.
Plot is nonexistent: MC lives with his mother and sisters and that's all.
The characters have a very simple personality, the single mother who loves the children, the tsundere sister and the innocent sister. MC exists just to fuck everyone, and all the women in town are potential sluts.
But worst of all is the grind, the mission asks you to talk to the mother, you need increase the affection points (and does not say how much you need and interactions sometimes give points, in other cases not), you need to talk with the person in place 'x', you need to collect more points...
The game is simple and doesn't stand out for anything, if you want to play the genre there are better options.
