Once Upon a Time... in My Heart (2016)

Both are crack dramas with super yummy male leads. They reject just about every lakorn stereotype. Both have beautiful soundtracks and gorgeous cinematography.

Both have charismatic gang leaders swooning over the pure and innocent damsel. Very unrealistic but oh so fun to watch!

Female lead and second male lead in Karn La Krang Neung... Nai Hua Jai are the leads in Prom Pissawat.

Both dramas are after betrayal (the main female lead betrays the main male lead because of a misunderstanding)and many misunderstandings between the main leads thinking they are both in love with their rivals .both dramas have employee and employer relationships.both dramas have clingy 2nd female lead

Lakorns. Mafia/gangsters. Romance. In "Karn La Krang Neung…Nai Hua Jai" main male lead is much more subtle, much more romantic. In "Le Jun Kai" main male lead uses physical and psychical violence towards main female lead.

Both are about a the female lead who looks like the deceased lover of the male lead. In beautiful flowers reborn the fl forget her past and live her life. Both dramas have a oddly pleasant to watch.

the same concept: the female lead saves the male lead, and the male lead looks for her. this is the more updated version(2016-2019)

This drama is similar to Khun Mae Suam Roy because
Firstly, both drama contain having girls with same face.
Secondly, complications betwwen both leads due to family.
Thirdly, lots of secret will come in light.
Fourth, story of second lead is also cute.

Both are romantic, action-packed dramas about battling gangs and a girl that unintentionally gets caught up in the middle of the battle of power. Both dramas have a girl that draw the attention of powerful gang leaders who are intrigued to the fact that the girl has no ulterior motive for helping them.
Both dramas have a main female character who looks identical to one of the character’s first, deceased loves. In Cruel Romance the girl looks like the main villain’s love from back in Japan. While in Karn La Krang Neung... Nai Hua Jia the main girl looks like the main love interest’s first love.
Both dramas have suspense, comedy, sorrow, and enough hand-to-hand combat and shootouts to keep you on the edge of your seat.

Both are mafia dramas, with male leads who have gentler personalities but have no choice but to be brutal. Female leads are naive and innocent. Both dramas have awesome production quality and unique storylines.

Mafia stories revolved around gang fight and people involve with the gang. Also both have love stories involved

Both of these dramas have a Mafia setting :)

share some actors and includes just as much action.
Mik at his best, has to choose between two women.
Both FL aren't rich, but very strong in their own way.
Both ML take care of their business. (hard shell soft core)

Tem o enredo tão chocantes quanto esse e uma estória de amor que desafia todos os perigos e inimigos.
