I see btw. Is it possible for the AkaneGF flag to be bugged? I initally went full rom on Akana but according to the Variables for the smartphone chats she is not flagged as GF. Neither the choice with Hayato + Akane on stairs or Akane / Manami in the corridor seem to have impact in this.
Edit: I'm using URM for myself to see whenever branchin happens
That variable I'm using it for the official Akane Girlfriend path, right now in her romance path she's not officialy MC GF, because that path is progressing slowly than her Netorase Path, where she's already his GF, so without NTR, Akane is still in her "Fake Relationship", there's a scene in the park where both of them are dancing, and she explains that is confused about what she feels toward MC due to the recents events, so I'm making more emotionally slow her Rom path.
If you're full Akane Rom, then probably unlocked her sex scene in the beach, if you make her speak more, she says that only is doing sex with MC because she wants to recover the control of her life, revealing her true intentions.
It is kind of deep her romance path, that skipping even a single dialogue can change a lot of things.
