At the end of book 7, you mean? Hell, I may be dead by then, lol.
I think the thing with M is, I saw it as a romance that would go from a physical thing (for those who were into it and those who weren’t would get M trying constantly, at least) to actual feelings, but if you can’t even get the physical thing for a long time (judging from M’s comment about it being a long game in the demo and Sera’s love of never-ending interruptions), and M literally could not give less of a shit about the MC until near the end, then there’s nothing to build on.
We recently were playing on discord with personality types and I was reminded that M is an ISTP, which are very physical people (and it fits them), but all of a sudden it’s going to take forever to get that? With A, you get instalove with resistance. With N, you get flowers and hearts and crap. With F, you get instalike with fun. With M? Action was promised and without it, there’s no interest. Not seeing an actual path to anything here.
