for all the hype prologue so far hasn't been fun, black screen for most of it and static images while the girls give us ntr vibes with how flirthy they are around each other, don't like senri at all and confused about memories that popped up after prologue when does it take place should I finish 1st chapter first or what? I played it first and it seemed like a scene in the present but I got the impression it skips mc meeting senri again for first time in a long while? at least that's what I assume from miu looking forward to meeting him again. everything is vague so far something happened in past but not explained and characters talk like we know about this or that and how it caused them to drift apart which is annoying
Honestly yeah the memories thing is a bit messy but it's simple once you get it: They are set in the past and you could watch them when they pop up, because they will be referenced later on in the story.
The VN really is pretty vague, lets hope answers come as the plot develops.
Though everything else in your comment kinda feels like you tweaking over nothing.
