Both drama is similar in sense of family dispute and marriage for getting revenge and unfolding daro secrets again families

Similar tragedy and boss assistant relationship
The story is quite similar and interesting
Introverted boss is better then rich man
Bith drama's has rich male lead and poor female lead

Fated to love you and Because this is my first life are great Romance drama with after marriage love story and romance, in both drama their is a contract between couple,
Highly recommend this drama along with other drama mentioned.
Both has interesting romantic story with little melodrama content and Comedy
