Proong Nee Gor Ruk Ter is similar to Yah Leum Chan:

Sai Roong is similar to Ya Leum Chan :
-Same FL

-Revenge from ML many years later with new identity

Revenge Type Lakorn, both the main leads use to love each other but both Johnny and Ann's mum force Ann to write a letter to break up with him while he was studying oversea. He got into a car accident.

The stories are very similar. The MC used to date, but because of an outside force, they had to break up. Both MLs hold a grudge over the FLs for breaking up with them, both are extremely jealous when it comes to the FLs being with other men, and they still love the FLs very much. Both FLs work for the MLs, who became successful businessmen. MLs use other women to make FLs jealous. FLs are hardworking who work hard to provide for their family

The story is almost same, but i think this one is more romantic than Ya Leum Chan because the female lead married a man only save his land lady's child(because she was in us and the landlady was in jail). Also she didn't have any baby from her fake marriage. The guy in this chinese series is really hot :P .

It has boss/employee relationship.

A possessive and jealous male-lead.

The last two episodes are spent with the male-lead groveling for all the shit he put the female lead through.

In both dramas the male leads wreak revenge upon the female leads for stupid unlogical reasons.

Both are Slap-Kiss lakhorns.

This one is very similar to Yah Leum Chan except this one is way better. The story is much more interesting. Again this is a revenge type lakorn.

Bad Romeo is similar to Yah Leum Chan :
-Teenage love separation through letter
-ML and FL meet again many years later
-ML revenge on FL
