RenPy engine would be more suitable for this game. Here are just random pictures or even 18+ videos. I don't know why Unity is here. There is nothing unique in this game. They could have made a game in HTML with the same success. Add the same character needs and it would have been essentially the same as in the game in Unity.
What's the point of this game? If this is a project for further good development of the other game from the developer, then ok, if the game itself will be in this style, then it's bad
