AUSSIE AUSSIE AUSSIE!!!!!
But wahhhh thank you very much for the kind words!! I'm glad you enjoyed the demo ♡ Also.... LMAOOOOO not Olivia found dead in a dumpster T_T I bet she's wishing you went to Ren's apartment instead... Maybe she'd have more of a chance at living lol /silly
I saw that another kind person has already answered your question, but just in case anyone else needs more confirmation:
You need to toggle on the NSFW feature at the beginning of the game, invite Ren over in Day 1, get him to sleep in your bed, move the pillow, then lean in to kiss him. You'll know you've reached the NSFW route if you see the "(18+)" label in your next choice.
