I installed the game and I've been playing it for a while so far, but only noticed now that I can never go "practice" with Sekai in episode 3. I'm trying to get the "First Experience" ending on ep3 but I can't because it seems like there are some lines missing. For example: on episode 3 when talking with Sekai, it only appears one choice "This isn't right" when it should appear this line aswell: "In that case...". And yes, I'm sure I'm not making the wrong choices so it won't appear purposely for me (if it can happen anyway).
Am I the only one? Is this some kind of error?
