All endings are done!
The story conflict is that there's an argument between two people. The player will have to choose the right responses to keep the relationship together. I'm unsure of how realistic I can make it as the closest I've gotten to romance is fiction. But now I need to write the argument without really mentioning what it's about as it ties into one of the ending lines. After that I need to write the routes connecting everything. I'm hoping to finish tomorrow so I can get to actually putting the game together.
I've been looking through several Ren'py tutorials and support forums to get ready.
