I know some people enjoy that kind of characterization or that kind of relationship, but this feels vaguely unsatisfying to me. I think it's because the particular quirks here (replacing words, masochistic lover) don't particularly appeal to me. The miscommunications here aren't unreasonable, but it means there's a whole lot of nothing happening here, so it doesn't really click for me. This is solidly in neutral territory.
My ratings on the series, from best to worst (with lines between 'enjoyed', 'neutral', and 'disliked'):
1-2, 2-3, 2-4, 6-4, 4-5, 5-2, 6-1, 2-2, 4-1, 5-5, 2-1, 1-4, 3-2 | 6-5, 4-4, 4-3, 4-2, 3-1, 6-3, 5-1, 4-6, 2-6, 5-4, 1-5, 3-3, 3-4 | 1-3, 2-5, 3-5, 5-3, 6-2, 1-1
