“I know how to be her Dom, but I don’t fucking know how to be her man.” That sentence alone sums up the MMC. I’m not a fan of contract based BDSM but I don’t think it really mattered to much in this book as it kept evolving.
FMC is an abused 21-year-old who felt immediate attraction to MMC. Same has he to her. He just made the relationship happen and didn’t sit around for it to come about.
