The author of this game did not create the story by randomly or purely through imagination, but rather it seems that they used direct experience to create the narrative. This is evident in the fact that many aspects of the game are incredibly realistic, which made it easy for me to see myself in the story as I played. In fact, even the facial reactions of the female characters were very strained, which added to the overall sense of realism.
I have played a few adult visual novels that were similarly messed up, and even before I started playing this particular game, I knew that it would be a different kind of experience for me. For those who have not yet played the game, All i can tell is it is very heavy and dark. The story of the game is really depressive but also impressive either, characters are realistic af I definitely recommend it.
