I seriously get put off my dramas that only focus on the lust part and ignore the storyline.. Many thai dramas have lot of abuse as a romantic trope/storyline which is extremely problematic but still some good romcoms (eg: Husband in law), few have good storylines too though they are dark (Hua Jai Sila recent version), average storyline but good chemistry (lying heart)..
Kdramas are conservative but good chemistry (something in the rain, one spring night) but k movies break away (eg: addicted 2002)...Jdramas have a good storyline and are a bit darker themed (eg: Perfect crime, Kenja no Ai)..
