Fun fact: In my original 1st playthrough, I didn't tell Ran about what Kaiser did at the beginning of Chapter 4. In the one that I sort of did out of curiosity, I did tell Ran and oh my gosh, it changed the entire mood for the rest of the chapter after the water bottle scene. Lamb put a -lot- of thought into your choices and consequences of those choices.
As for the choice that sort of gave out a little more information, it's...somewhat near the end or Day 3, I believe.
I'm not sure if the MC knowing the RFA is real or not. She was kind of having a somewhat "fever dream" I think, and I'm not sure we can take it at face value. But! Maybe I'll be proven wrong~
Well, Raze did mention something about a prize and he seems pretty intent of getting it back. I wonder if Esmius managed to steal something that Raze holds dear to himself.
Funny enough, I haven't actually played Esmius route in Ice Demon yet, haha! I've only played through Sirath's route. (Which I totally fell in love with him, not gonna lie)
