Meowchi:
I saw that you haven't watched My Mister (ahjussi romance but not romantic) yet! If you loved My Liberation Notes, Our Blues, Summer strike you'll like Call it Love, Lost as well, cuz I loved it too!
Another one is Nigeru wa Haji da ga Yaku ni Tatsu somewhat different in respect of others mentioned but you'll get adult being emotional, solving problems and overcoming the hurdles, compromising to be better in life. I never thought I would LOVE this!
FYI: The on-screen couple here got married off-screen irl after this drama, isn't it adorable! <3?
Here's a list I created for the adult melo lovers like me: https://mydramalist.com/list/4Ko5WNY4 (I update the list every now and then)
Yeah, I haven't watched My Mister... I have been considering it, it's just that my friend (whose taste and opinion I usually trust and respect!) hated it so much that it made me doubt it. I'm not against making up my own mind about things though! :)
I'm interested in Call it Love, if only I didn't have to get yet another streaming site to watch it. :p I see that Lost is on iQIYI though.
I have watched Nigeru wa Haji... as well as many other titles on your list, but not all of them. Awesome list! :)
