Out of every ship i have been invested in, which isn't a whole lot but still, I think that narumitsu is the most justified in being the most painfully slow burn to ever have burned. Like, it's obvious to literally everyone around them that there is something between them but it still takes twenty years to do anything about it. Not because they're stupid but they're both just specific types of fucked up that make getting into a relationship kind of impossible.

They're both seemingly very reluctant to get into any sort of romantic relationships in the first place, one due to general disinterest and a truly incredible amount of emotional constipation, and the other due to his last (and only known) relationship being so fucked up that he kind of gave up on the concept entirely. Them being excruciatingly in denial about being in love for decades is just so in character because they're just Like That.

Their history is also complicated enough to warrant waiting around for each other forever, there's so much baggage and trauma and hurt between them that it's just crazy. They've saved each other and they've hurt each other and they push each other away, they owe each other their lives and their jobs and their hopes. They would do anything for each other but are still pretty justified in being afraid to take the last step into making their relationship not just platonic.

idk it feels like a lot of other ships fall into the infuriatingly slow romance because the characters are too stupid to take a hint and it's just kind of painful after a while but these are the most hilariously repressed characters I have ever seen and while they might be stupid about their own feelings, it's usually stemming from trauma which is far more interesting for me personally lol.
