Hello!
I’ve been itching for something in the vein of the FMC being head over heels in love with MMC at the start, but like how it is in most cases (idiocy), he hurts the FMC really badly and she becomes SO disillusioned and hurt that she’s just “meh” about him and his touch no longer turns her on or she feels distant with acts of affection, including sex, like she’s just painting watercolors in her head when intimate or like “damn, here :|” when he wants affection. No butterflies, no body betrayal (at least not until the latter part of the story). INDIFFERENCE is the vibe, because anger is a piece of cake stacked against it. I want the regretful MMC to feel her disinterest to his very bone and desperately wanting to set things right with her.
