Quick question, will there be a option to get 18+ scenes with ren later on even if you don't do it early in the game. I'm trying to have a bit of a slow cute romance that later turns like that. I just didn't want to bed him on day 1 lol xD
Unfortunately, the 18+ scenes don't impact the storyline in any way, so I haven't given them much focus or attention. As such, the only way to unlock all of the spicy scenes is by sleeping with Ren in Day 1.
If it's not too much of a hindrance, you can always sleep with Ren during day 1, fast-skip and pretend it never happened, and sleep with him again once you're ready! Ren won't ever explicitly bring it up afterwards, so I don't think it'd be too immersion-breaking.
But if I ever come back to the 18+ scenes, I can look into adding an additional checkpoint during Day 7 or something^^ Thank you for your feedback!
