Hi again!! ^^ I'm sorry if I misinterpret your question, but I don't really understand what you mean by "they were identical in both playthroughs"? ;v; Were you talking about the interactions during the spicy scenes? The interactions you're supposed to have in order to get the spicy scenes? Or the interactions after you receive the spicy scenes?
Regardless, thank you for your feedback! However, I doubt I'll be doing anything with the spicy scenes anytime soon — since they don't contribute to the overall storyline nor does it have any benefits for any other character besides Ren ^^;
