The Tale of Nokdu - was a nice watch. actually goes by pretty easily, not really heavy and has likeable characters. the humor was good too. solid but nothing ground breaking.
Her Private life - I'm not fully thought with it but it is actually quite nice. the main setting takes place in an Art museum. against my expectations the fangirly stuff from the female lead isn't annoying and the chemistry between the leads ist also good. what's nice about this is, that the male lead isn't that narcisstic and arrogant prick but actually quite nice, maybe a little introverted,This drama doesn't seem to be the mega burner or groundbreaking but it is a solid watch.
edit: oh i forgot ONE!: "Crash Landing on you"
this show had a VERY strong start. The first episode is very very good and you keep graving more. It was especially interesting setting wise - to see how a k-drama would visualize the life in north korea and how it would adress certain (heavy) topics in front of the backdrop of a romentic comedy drama. This is the newest one of Park Ji Eun (You who came from the stars, legend of blue sea etc.) so you can expect a very good chemistry between those (top notch) main chars. The female lead reminded me a little bit of the character cheon song yi, altough a more mature and businesswoman version.) It flattened out at the end for me and i pretty much forwarded mostly through the last few episodes. But maybe especially because of its extra ordinary setting it is worth to be watched at least once.
(sorry these are the only dramas from your PTW list I have actually watched ^^')
