Your comment is like a breath of fresh air. You're definitely not the only one who thinks along these lines and it's reassuring to read this point of view, that's realistic and not oversanitized for the sake of adhering to some pseudo-moralist checklist of healthy characteristics in people and relationships, that's weaponized against anyone who dares to present different ways of existing. And that's when you analyze its events on irl standards (which is fine to do ofc), let alone it being a fictional work for entertainment and not educational material on bdsm or relationships in general.
Life's not black and white, strictly divided into perfectly healthy or unhealthy. As long there's a decent balance of needs being met, feeling fulfilled, safe and trusting the other person, there can still be questionable practices or preferences that can be worked through in time (quite abit of time usually) and aren't an automatic deal-breaker for those involved and affected.
They're my kind of broken together. "Broken people being content together in an unhealthy way" lol I can't be the only one who's loving this. Bottom is an adult who made his choice and consented to this and he doesn't exactly seem to be complaining either. Having done stress relief sessions irl, I get it. Bottom is happy being able to help somehow and I won't take that away from him by crying about it being "unhealthy" because we already know this isn't a representation of "good" bdsm.
