Man, thinking about that specific dynamic unlocked so many weirdly specific fics for me. It's less about the act itself and more about all the emotional baggage that comes with it in canon, right? The whole forced intimacy thing, the violation of it being unintentional but also creating this undeniable link. I've seen some authors just nail the aftermath--the quiet horror of suddenly having someone else's memories bleeding into your own, or the awkwardness of sharing dreams.
One that stuck with me was a 'Soul Eater' fic, not even centered on Maka and Soul, but a side character perspective watching them navigate it. The author focused on the subtle changes, like how Soul started unconsciously mimicking Maka's book-organizing habits, or Maka picking up his guitar chords in her sleep-talk. It was all about the quiet erosion of personal boundaries, which felt way more profound than any big dramatic confession scene.
There's also a subset that flips it, exploring what happens if the kiss is intentional but still a soul-deep violation, like one character using it as a last-resort weapon. Those get seriously dark, grappling with consent and power in a way the show only hints at. I'm way more into those psychological deep dives than the fluffier takes.
