Ngao Ruk Luang Jai (2010)

Tricky in Love is the remake of Ngao Ruk Luang Jai. Fun fact: NRLJ was the debut of all 4 main lead actors while TIL is the debut of the ML Au Kittipon Tippayatayarut.

Both are about an intense love triangle with two hotties fighting for a beautiful girl

The plot are REALLY similar to each other.

*In both the FL are orphan living in the orphanage,her real family are rich people.
*In both the jealous Nang Rai takes the FL´s place by stealing her necklace..or something.
*In both the FL have a guy friend that is in love with her,both are injured and wants to get a cure so they can protect her.
*In both the ML and FL bicker and fight against each other,since the ML´s family wants to buy the orphanage.
*Both ML´s fall for the FL pretty quickly and does everything to win FL´s heart and consider her guy friends as their rivals.

Oh..and there are some more similarities.
