I don't watch many purely romance focused shows or movies, though once in a while I do watch a cliche hallmark christmas move hehe, but if I had to link sevngjn to smth I watched, I think of my favorite anime: fullmetal alchemist brotherhood!
I absolutely love mustang x riza and when I think of fire I think of hyvnjn plus with mustang's ambitousness I think hyvnjn fits him well and sevngmn is the more calculated and serious-on-the-outside goofy on the inside and has an unconventional way to show care to ppl, so that fits riza!
Another similarity is that riza and mustang, like sevngjn, are more aloof around others, they don't openly show their affection, but it's the subtle things that show how deeply they care about each other (the scene where riza knows it's not mustang bc he calls her by her name instead of her title in private!!!!!!)
