I have all the achievements completed except for the "complete all of binary star hero" ending. With low affection points, I went for the window and door with no interruptions from the other love interests. I'm not sure what I'm missing.
To get this achievement you must play all of the bad endings and the side stories as well :)
ohh I see, thank you. I just had to do the side endings. Also AMAZING art! The story is great too
