I wouldn't have even started this one, based on the AO3 tags, if I hadn't enjoyed a number of others from Copperbadge (a.k.a. Sam_storyteller). Turns out, the writing itself, and the emotional depth, are as good as ever, so I liked the initial stages well enough (2.75±), when it was just about what's apparently called "service submission" (control and caretaking), especially since there's some mutuality. However, I'm afraid I just can't enjoy reading about pain, one "good guy" getting whipped by another, et cetera — the final coda (post-CA: Civil War, which, BTW, I have so far, deliberately, still not watched) gets serious in the D/s depiction! — even if it's what he wants. I read even that final chapter, despite the clear, specific warnings — I guess to see how I would react — but concluded that my horizons are broad enough. I'm afraid my inner voice is a bit judgemental, not that either of them is "bad", but that this is not an emotionally, psychologically (nor, obviously, physically) healthy "therapeutic" method for getting through difficult circumstances.
