Yes, that was a little off-script slip, but I'll address it soon. When I switched from a visual novel game to a sandbox, some paths remained uncorrected. Just like some scenes are incomplete. I will soon finish these pending issues.
Would this be why when on the "Normal" route, when Olivia has the talk with MC about going to the water park together, and maybe some other stuff (I can't fully remember the exact conversation that happens)... that never actually happens?
She enters the room, tells the MC she wants to talk about 'it", they sit on the bed, then it goes to the choices... no discussion at all. Had I not played another path previously, I'd not have known anything what the talk was about.
If you play the "Dark" path you will have the chance to share if you want. So far what's in the game (that I came across, there might be more) is a section of Truth or Dare, where you can share either LI with your friend Ryan - as a dare, or in the conclusion you can do a 3some or 4some with him involved.
As stated - if you play the Vanilla route, that won't happen (neither netorare or netorase). On the 'Normal' route that can still happen I believe, though not sure if it will stick to netorare only or have both netorare and netorase.
