Well I already got the sweet ending, but how do I get the other endings listed there? some step by step?
There's a lot of different ways to do end of Rye's route during the 5 days and it also depends on the choices you made during the party, so a step by step guide isn't really needed.
Sweet end - Rye convo #1 determines if you get this.
Bound - Rye convo #2 determines whether you get bound or not.
Bondage Basement end - Can get this end in Renee's 2nd convo or if you don't defeat Renee and ask her to keep you.
Rye Just Business end - Talk to Renee and accept her deal to get this (it was also possible to get this end earlier in the game)
War Camp end - Don't resist during Renee's Masterstroke scene (lots of other ways to get this end)
