My dear MDL friends; 

Aniong

Can you help me with recommending some emotional Kdramas about Poor female lead who sells her body or soul because of money . I'd  like to watch Kdramas in which innocent or good poor girl transforms to a bad girl by degrading her pride or values in life and sells her body or soul to gain money or get rid of her miserable living situation.

Hmm maybe sort of: Ladies of Storm, Temptation of Wife, Glamorous Temptation, Fates & Furies. All longer kdramas though. For shorter sort of is My Mister.  Something like you want is more visible in thai lakorns.
