Not a neg whatsoever, but this is so, so, so WattPad-coded. ("tongued danced for dominance" – so good, we're only missing describing eyes as orbs...) It's not a neg because who amongst us doesn't enjoy a cheesy enemies-to-lovers story every once in a while, especially when it's clearly made with passion; the enjoyable character drama simply sweeps you away, and despite the recurring "some time later" title cards probably making the structure seem more fragmentary than it actually is, the storytelling stays propulsive throughout.
The only thing I'm not really sure about is how much of a background element the "teaming up against a bigger threat" conceit ultimately feels like. Some potent drama is left unsqueezed, I think; I can imagine reading a version of this where it forms a bigger part of how Kojika justifies keeping Stag around both to himself and others. Still, the central romance works as is, and I think it's enough to carry the story.
For the standards of fantasy, everything is pretty economic and utilitarian here, which largely (but only largely) feels like a strength. Points for keeping the scope manageable, at least. We learn just enough about our main characters either directly or by inference to give their interactions material to work with; a big part of the game's appeal is just seeing how Kojika's and Stag's dramatically reshaped relationship affects their daily lives, and all that is indeed pretty fun to read about. I hope we see Stag's fashion montage visually in the Disney+ adaptation. On occasions, I wondered whether getting a clearer impression of the main duo's shared history (if not involving face-to-face meetings then at least them hearing about each other's exploits) would have been interesting, but in general, everything more or less works on a character level.
Where the sort of fast-and-loose worldbuilding starts to hurt, I think, is that though it's of considerable importance for both, the conflict our main characters fought in is sketched pretty vaguely in basically every way: causes, consequences, etc. There's a lot of talk about "a better world" and the opening notes that Kojika stands for "justice", but what is it that we're actually fighting for here? Is this a religious conflict, or a philosophical one, or just about politics, like a crisis over disputed royal succession or something? If our heroes are seeking to depose the tyrant, what is their plan for after? Are they ending monarchy, or do they have a new king in mind?
I think it is pretty clever how the plot sidesteps these questions by essentially starting at the end of another story that would have explored them in more detail; and yet, I feel like it's stuff you can't simply ignore with these specific characters. Dido's motivation of personal revenge works, but as far as Kojika and Stag go, I would have liked getting something more concrete – doubly so when the story gets into some big moral conflicts it mostly papers over with the power of love later on.
Finally, a couple quick notes about the presentation: I love the customized jam sprites, and Stag's design feels like it was made with the entire character profile in mind. It's so good how the outfit change transforms the entire vibe. The UI is pretty messy, really all over the place stylistically – I think the base is just too modern and the customizations too light. On the other hand, in terms of sprite animations during the sex scene, the attention to detail is lovely.
