I get that a lot of people are unhappy with the twins. They are characters that were created by a friend of mine who passed and are designed based on a character from another popular VN. My friend helped write the dialog for them in the game, based on how he envisioned them. Out of respect, I chose to not make them love interests or even side girls, per his request. I am going to respect the wishes of my friend. However, the original plan was to bring them in and then they would get a separate story down the road. That idea has now been scrapped due to the hate I have received about them. They will still have their planned role in the story and will show up in a few future chapters for key plot points, and then you won't see them again.
