Elena and JB are open minded, but love eacher other. They both like the MC and the MC do like them... Elena is flirty towards the MC and vice versa, but not more. (with tzhe total consent of JB, he even likes that)
No matter how you go in the game, there are ZERO romantic feelings between MC and Elena, absolute none. Its all about a bit flrting and for the fun... overall, they are creating a very good, healthy and fun friendship. I dont think there ever will be "more" than that. And it doesnt seem that the MC thinks otherwise. There are a lot of inner monologues in the game, and MC has some deeper thoughts about some girls, none so far towards Elena... except those "quirks" they have. Which is nothing that would lead to something serious between MC and Elena.
Camila is another of the... "main" Sidegirls, or more important sidegirls where there is no real deeper thing going on... she has fun with the MC and vice versa. And they have a good friendship... but romantic feelings? Not really. Many hope and think that there might be something between her and the MC in the future, but i dont think so... its a bit late to initiate something in that direction. She is just a good friend who seeks fun, and with the MC fun between the sheets aswell, without to much attached feelings going on. Girls wanna have fun, and thats the main thing for Elena and Cammy. No romantic options for the mc, iam pretty sure of it.
And even if not EVERYTHING is perfect between elena and JB, which is perfectly normal... i dont see any kind of friction between those two that would seperate them. Again,,, its a bit late to create that either.
It will be the last episode for this season and after that the game will be a lot different... nothing new will be created anymore. Things will go its way, but dont change direction to much anymore.
There are already some romantic paths intiated with many sidegirls, but those who did not have such development will no get those in the next episode or ever. Not every girl will be dateable, and that is a good thing. Elena is one of those. And i think cammy too...
