Both are short crime dramas involving teens, with blackmail, broken families, and all these elements.
Both start with A crime reveal that leads to a butterfly effect and end up ruining everyone lives.

Both are very well made lakorns revolving around big families...the atmosphere is very different but both are enjoyable.

Same writer and main lead, while the plots are completely different, they both have similar atmosphere..one sided crush, female lead getting bullied at work, gentle male lead..etc.

Same writer, another well written family drama with main lead as "Cinderella/Candy" hard working character with Makjang elements.

Golden Time and Surgeons are on the same line for me...very realistic with great acting...actually Golden Time is a lot more detailed but Surgeons had a satisfying romance element...if you like one you should definitely check the other.

Her Legend is about making bags while Come Jang Bori is about hanboks...both are Makjang dramas where the 2nd lead tries to take the female leads place in her family & tries every trick to win over her talent...the male lead in both is the playful heir who's always their to rescue the female lead!

Both revolve around making clothes...in both the female lead always competes with the 2nd female lead who tries every trick to win!

Both the lakorns are Rom/Coms that has the contract marriage theme...in both the couple hate each other at the beginning but being forced to live together in the same house they start falling for each other...in both there's an annoying 2nd female lead (the girl the male lead originally loved) trying to steal him back!

Both dramas depict unexpected pregnancy due to one-night stand...In both the couple get married with the condition that they'll divorce after the delivery of the baby...in Oum Ruk...the male lead is kind and warm...always trying to take care of his wife who's still in love with her ex...while in Fated To Love You...the female lead is the one trying to get her husband's heart...in short...they depict opposite situations...but both are really funny with many sweet moments!

Both dramas are about a career woman...known to be tough & cold...is lost between the Sunbae she loved for a long time & the younger man who comes to live with her...Who will she choose in the end?
