This is a bit complicated, but the short answer is 'Yes-ish'. Let me explain.
Ignis was always meant to be in love with Seeker. This has been the case since the very first draft I posted of the game back in 2021, one of the very first things you learn about her is that she is attracted to him, and he has yet to reciprocate.
And their relationship has always been an integral part of the story. The way Ignis and Seeker trust each other, the way they interact, and, being honest, and the way they both care for each other more than for the rest of the League combined has always been something I intended to be part of the story. Ignis and Seeker have the deepest relationship of the whole cast, they have changed each other, and, in more than one way, they complete each other. Ignis is the first light in Seeker's life since Victoria stopped being around, and Seeker is... probably the only reason Ignis is even around.
At the point the MC joins the team, I don't believe Ignis or Seeker could function without the other. They don't know how to not need each other any more.
There are two big reveals in Book 1 of AToH. One of them has to do with Aki and Forlorn, but the other is Seeker's, and approximately half of it is dedicated purely to Ignis's reaction, to her proving how inexorably the two of them are tied, and to showing that there exists nothing in the universe that will make them ever let go of each other.
Originally, AToH was only going to have three romances: Aki, Latooni, and Nova. A lot has changed since that idea, but those are the three I always knew I wanted to write. I received a bit of backlash because of that, stuff like 'too few options', 'only one male RO?', and even complaints that Aki and Lat were too basic, or... too overused (I have played every game on Jason Hill's platform. There is no character in there like Aki).
I don't begrudge people who made those comments. Criticism is how authors grow, of course, and those comments helped me grow. I ended up creating Iris, expanding Mars' role, and sidelining Dark Star.
But I overcorrected. I began to consider if Ignis and Seeker's relationship couldn't be written platonically- after all, plenty of superhero stories make a big point of the bonds of friendship. Ignis and Seeker didn't have to be a successful Batman and Wonder Woman, they could just be Goku and Bulma, right?
Wrong. The more I thought about it, the more I realized the climax, the reveal, the characters themselves don't work without both being desperately in love. If I don't have Ignis and Kratis declare they love each other at the game's climax, then there is no point to writing the story. It took me a while to understand that, but I did, eventually.
But as you can obviously see, that didn't mean the MC's relationship with Ignis was scrapped.
And the fandom has a lot of takes about that. Some are subtle, some are not. Some are hostile, some are not. Some are rational pieces, others are impassioned comments.
But the one thing they all have in common is that they're wrong.
I am not writing the path as some sort of punishment, or exercise in hurting the reader. It's certainly not done because I want to scam whoever ends up reading the story, or because I 'don't understand what a RO is'.
I'm writing the Ignis RO because it serves the narrative. It is probably the path I spend the most time thinking about, it has the largest build-up, and it is the path that has the biggest pay-off in narrative weight.
If AToH was to have anything close to a 'canon' path, Ignis would be it.
I hope that answers your question. Thanks for the ask.
