The shows I would recommend for newbies ..... different types of shows.
Secret Garden - One of the best Korean shows ever. Tropes include “girls like the arrogant guys”. Body switching.
Rooftop Prince - Time travel sends prince to modern time where he meets the dopplegangers or reincarnations of his murdered fiance and her sister.... Very funny in many places because the guys from the past each wear their own colors, some called them Joseon [era] Power Rangers.
Dream High - think Glee without the gay... light-hearted fluff. If you like that kind of thing.
49 Days - Girl in coma is told by the reaper that she has 49 days to gather the tears of 3 people who truly loved her (excluding family) or she will die (before her time). In bhuddist culture they say your spirit hangs around for 49 days before it moves on.
.........
and you’ll need at least one show where girl pretends to be a boy :p
“You’re Beautiful” (another translation was ‘She’s a handsome man’) PLUS: Park Shin-hye! or “Coffee Prince” would do well. PLUS: Yoon Eun-hye!
Yo, GeronL ... Hanguk isomika ?
Netflix has some of them and Hulu picks up most of Drama Fever’s shows(not Running Man, though).
My favorite is “A Gentleman’s Dignity” and I just finished “Flower Boy Next Door” (also stars Park Shin Hye) and thought it was great. Heartstrings is another musical one, set in college (more Park Shin Hye). The lead guy and the drummer are in a band together in real life and they aren’t too bad. I would love to see them live.
I also loved “My Husband Got a Family” which isn’t available in the US.
