Thanks for the recommendation on Florian's route! I might consider it and I'll get back to you if I do (I kinda wanna get the Good End for every route at least).
I'm also glad I could put into words what was frustrating to you about Enix's route. It's just such a shame about it because Enix easily my favorite character. Him and Luna having a pre-established relationship allows for scenes and moments that other characters can't have with Luna. I don't even have a problem with drama in general (I do have a limit though. If it's angst/tragedy just to try to get the plot moving forward or just for THE SADS, I hate it), but it has to be done well and with a lot of care.
I honestly applaud the developers for episodes 1-8 of Enix's Story because they're amazing, but then the ball drops so hard. It's not that I couldn't recommend the game for anyone (I know there would be people who immediately feel sympathy for characters like Isla or enjoy antagonist redemptions because "eVeRyOnE dEsErVeS a sEcOnD cHaNcE" or whatever), but it really is only for people who feel okay with being dragged along by the hand from beginning to end. I think it makes it easy for people to pick favorite routes because there isn't much choice in where you're able to go, but if there was more choice involved, I could see people liking everyone's route more overall because they felt like they had agency and at least some control over where things went.
And the last three chapters don't even make that much sense? The whole thing with Isla crying her eyes out (Which still earns zero sympathy from me. She slapped Enix in the last episode and bullied Luna for dating Enix when "he was already dating someone else" except Luna didn't do that and tried to stop Enix until he explained that he broke up with Isla, so Isla is delusional, which is another sign that she can't be redeemed.) and telling Luna to let Enix go is her basically saying that she doesn't care about Enix's happiness. Then, like two scenes later, she takes it back because Enix is miserable, despite him being miserable for years beforehand???
(Also, it's weird to have a scene between Enix and Isla when Luna isn't there and this is supposed to be from Luna's P.O.V. I'm convinced that it was only to try and get the audience more onboard with Isla's redemption and it still didn't work. There are a couple scenes like that in Jamie's route too and I've always found it weird, but at least those are more Luna leaving the scene so she was there at one point. Just--why make a "His P.O.V" section at all if they're just going to jump to their non-Luna scenes anyway?)
And Luna trying to get Enix to go back to being a doctor is so forced. Enix even stares at her expression and asks if Isla talked to her (which tells us as an audience that Enix knows that Isla is terrible and full of garbage but sure, redeem her anyway) but Luna denies it. The whole scene has to go a very specific way because clearly neither of them want this and just a little edging from either of them would cause them to break. Luna's whole thing throughout this entire route was, "I don't want Enix to do anything that doesn't make him happy," and now she's doing the opposite? Yes, he won an award and yes, he's good at it, but Luna already knew that he would've made a good doctor and didn't care because his happiness came first and that's what Enix loved about her. Enix already established pre-Episode 9 that he tried to fool himself and tried to be happy with being a doctor and he couldn't, so this is just a waste of the player's time.
That's why I brought up my thought of Isla and the family directly involving themselves with threats and force, because Enix and Luna have come to too much of an understanding by the end of Episode 8 for this to happen without testing the player's suspension of disbelief. In the original here, when the player sees this scene with Luna trying to tell Enix to be a doctor after everything, they just go, "okay, this is dumb, this is just needless drama so that there can be Good/Bad Ending options," whereas the family interfering would instead bring a feeling of, "this is a terrible situation they're both in and it's understandable why they're conflicted on what to do about it," especially when Enix used his money to buy Luna that laptop and cutting off his funds + the threats would seem like a legitimate problem.
Leaving it up to Enix and Luna to cause the "break-up" isn't natural after they confessed, had sex, and were basically already onto making their game. Isla goes from an "I love to hate her" manipulative character to a plot device to force Luna's hand. The game basically has to do a 180 swerve to desperately drive the plot to where any sort of Good/Bad Ending is possible.
And I simply cannot forgive the game for punishing both Luna and the player for enjoying the moment. Isla was set up as an antagonistic character who the player was waiting to see get her just desserts, and then as soon as we get the satisfaction of seeing it happen, the game was like, "Yes but actually no. She's sad and you should feel sorry for her and Enix and Luna will be expected to forgive and thank her by the end even after she made both of their lives miserable for literal years."
Also, if the witch had this destiny book and Luna asked for a romance, why didn't the witch just look up Luna's soulmate and use her magic to put Enix and her into more situations together? Yes, the destiny book isn't for "mortal eyes," but she could've interfered without telling Luna directly that Enix is her soulmate.
The whole filler thing really just amounts to Enix's last three chapters not meaning anything. Marcello's (was told by a friend) reveals stuff about what's been going on behind the scenes and Jamie's actually reveals a lot about his backstory. Outside of what happens with Isla (which, again, I don't care about anyway), the only thing that happens directly between Luna and Enix is the reveal of what happened with the spell, which is just not enough content for three chapters.
I don't know if the DLC for this game will be paid or not, but if it is (and I know I said this before), I really do hope they go back one day and then release a "Deluxe" version of Love Spell, sort of like all those Wii U -> Switch ports.
All the DLC already being in there, more choices that actually impact the game, at least two branching paths for the Good/Bad End (like redeeming/not redeeming Isla for Enix's even if I don't think she'll deserve it regardless, and and maybe a path for Jamie's where he either continues to pursue music or goes with the Kitty Cafe that his bio hinted at instead), and just an overall experience that people would enjoy more because they have more agency.
