Based off of "Game Tomodachi no Onnanoko to Onsen Ryokou de Yaru Hanashi NTRver." this is a spin on if Sakamoto had discovered Mari's cheating, and had it come to its natural conclusion. Reading the original for more context is advised (if you're old enough, its 18+ obviously), but this story works on its own as I believe I give enough context. I took a lot of inspiration from Synepeies for this. This is also my first story I've ever written, so please point out any flaws or inconsistencies you notice! I am by no means a storyteller, but only through experience can you grow. Who knows, I may even write one related to the one based on Frieren released by Ahemaru, since that one really got on my nerves too.
