I have been reading the "My Mister" drama and this thread on the forum six years later, yet many of your comments remain relevant and interesting. I particularly liked these two points you made, as I share the same opinion.
I practically know this drama by heart now. I've written a lot about it on my Polish site about K-dramas (https://k-drama.pl). It's so addictive that now I find it difficult to watch anything else. Everything else seems trivial. As therapy to emotionally disentangle myself, I am writing my own version of fan fiction. If you're interested, take a look.
