Well I think player tops Nauxus happened before MC went to the snow mountain. As the patch notes said that " After you have sex with Nauxus, you can invite him to the bathhouse during the night time.". So it doesnt matter that the MC went to the mountain or not.Are the Bonus contents actual events that happened or are they just fanservice? I'm curious about it cause in the latest CG where the Player tops Nauxus, he says that it's his first time bottoming yet in a teaser image for the 3rd Bonus content featuring him and Thane, we see him as the bottom. Now, that could've probably happened after MC topped Nauxus but I'm also willing to bet it most likely happened during the 6 months MC was gone.
