None of those series appealed to me, and am surprised by your praise for the IRIS sequel. In the 11 years I've been watching #KDrama, that one has been universally lambasted as an absolute turkey. You're literally the first I've ever heard praise it.
I HATED the 1st Strong Woman for its brazen misogyny, so was never going to watch a 2nd season. The ONLY #KDrama I've wtached with more than 1 season was Forest of Secrets - which, to be fair I scored S2 higher than S1
