i'm not a big fan of yamapi either but i really like gakky (aragaki yui) so i tried. idk about medical accuracy but the characters were pretty lifeless and that's dealbreaker.

about jin, i read dramabeans' recaps of korean ver and the drama seemed so ridic and character so dumb it's a wonder he still lives. but apparently japanese is way better, so i'll def check it out. thank you :)
