This is really the pinnacle of NTR writing. Like where do I even go after this? Nothing can top this. The way I feel about this story is almost the same as how I feel about my favorite non eroge stories/games. It lives rent free in my mind. The characters are excellent; they're layered, lovable and hilarious. The atmosphere / music choice is excellent, the overarching themes are absolutely perfect to explore for an NTR story. This is like avant garde NTR, everything else is so bare-bones compared to it.
I'm not even into Erin x Mars stuff sexually as it doesn't really get me going, but it is my favorite part of the game simply for how sweet and heartwarming it is. Erin can find healing and a semblance of purpose again through Mars, as Mars can find redemption for his past sins / all the hurt he's caused through helping heal Erin. Such a great juxtaposition of the main characters. It's like an antidote for all the pain this genre usually entails
I will read anything this guy writes
Btw Ceci, Erin, and Mars are the best characters
