American Fan:
I'm out of touch with the newest series that have come out.
In terms of currently airing series, I'm watching and loving "ThamePo" (my current favourite, all-around excellent - plus surprising depth from GMMTV), "Your Sky" (adorably cute!), "Fourever You", "Perfect 10 Liners", "Sangmin Dinneaw" and "Heart Killers" (although I'm not quite as enthusiastic about this one as most others seem to be).
I haven't yet started on "Boy Next World", but those who have seem enthusiastic.
I'm also watching "I'll Turn Back This Time" and "When It Rains, It Pours", but these have only started airing, so it's too soon for me to have an opinion. The lead actors in the former are the side couple from "Meet You At the Blossom", which I recall that you liked. The latter is a JBL, so probably not your cup of tea.
So basically, I can recommend any of these to you except for possibly "When It Rains". This should keep you busy during your convalescence.
P.S. Your brother is absolutely right! See numerous articles on America's opioid epidemic.
