I mean...fair enough, if N_Taii's intentions with the freeroams was to show us that Lily is just naturally that much more lewd compared to other girls where, after losing her virginity, she can immediately accept the fact that from now on she's going to be having sex with her boss whenever he feels like having sex, then sure, the freeroams do make sense...kinda, i still feel like they're too advanced for current Lily, both in quality and quantity, and it also kinda cheapens Lily's whole corruption for me a little bit if it's true, but at least there IS an explanation for them this way.
Personally, i think that the answer is infinitely more simple and it also proves what i initially said to be true (that Lily is not caught up at all), i think that the the only reason why we got this many freeroam events for Lily that are this advanced is because everybody else is already having sex wherever and whenever they possibly can, like for example how you mentioned that Rose has already got like 7 active freeroam events at the same time and 8 is the maximum anyone can have, meanwhile Lily had just gotten her very first sex scene ever at the end of her latest quest, and so i feel like N_Taii saw that and realised that he's not gonna make content for Lily anytime soon again, so he decided to add these freeroam events so that it's there for people to watch while he's working on the other storylines.
tl;dr: You're saying that the freeroam events have a narrative purpose and i'm saying that it's basically just fanservice so that people who wanna see more sex scenes with Lily don't have to wait until Update18 or possibly Update19 when she gets a new quest.
I'm just being annoying at this point but if i'm right and this was only so that people got more Lily content in-between quests, then i absolutely do believe that the 2 part freeroam event where in the morning Lily and Nezar are having sex in the Greenhouse, and then later that same day they're fucking in front of the Tavern inside that toilet, those freeroams should get pushed forward by an entire quest, and they should only unlock once the player plays through Update18 (assuming that Update18 is the next Lily Update).
