Because of You (2017)

It's the same plot line, and everything just the Chinese version

FL got swapped from birth
one ends up in a rich family, other in poor
antagonist tries to prevent FL from finding happiness
foster mother mistreats FL after she finds her biological daughter
biological mother of FL also mistreats her daughter
female leads fight for the same man
step-brothers compete for their dad's inheritance

In both dramas :
- Single Mother Female lead (others child)
- Nice Male lead
- Hardworking Female lead

similar idea that the FL is lost/abandonded as a child.
evil jealous step sister that wants everything that belongs to the FL.
Both ML and FL for both stories have met and known each other as a child and now have fallen in love as an adult.

Long lost granddaughter found by her grandparent and she apparently seem to be a princess, while BoY (chinese remake of come jang bo ri) the girl gets left behind, loses her memories and gets sort of 'replaced' in her own family by the daughter of the woman that took her in.

sisters/ family- both dramas contain sisters that fight with each other but due to different reasons.
female lead living in a poor family with the male lead in a rich family
ML and FL of both stories have met in the past but then reunited but don't know each other until later.
love/hate

Both FLs are selfless and mistreated by their families. Although The Little Nyonya spans across two generations both dramas revolve around feuds, lies and betrayals between family members. Both FLs through determination change their destiny despite the misfortune they encounter.

both have a missing daughter theme and they missing daughters end up with their lovers they both have a complicated past with an accident that resulted to the lost daughters

-Not very much similar in any aspect, but they both have it where both leads take care of their kids
-Both couples are very cute
-They have amazing chemistry

The plot and romance are very different but I am getting the same vibes so far

Talented FL with no education that strugles to make it
abusive foster family that FL still loves and helps
FL that stays true to her value despite all

Kind female lead who doesn't get along with the main guy at first; they meet again years later.

In both shows, the ML and the FL met at a young age. In both stories, the Female leads worked hard to peruse their very own career and passions, while the male leads are usually always there to support them. Both shows have their share of comedy and sweet moments. While Because of You have more family drama and Love is Deep is about walking out of a past romance, both shows give out a similar feel when it comes to the main couple.

Both dramas have female lead who is long lost children of wealthy family. There is also someone who acts as this lost child, but in reality isn't one. Adoptive mother is favouring her biological child. In each of these histories secret is involved.

O Drama traz como personagem principal crianças, fala sobre adoção, família, ambos tem nacionalidade chinesa.

They both have about the same plot line. The main characters get their rich life switch with someone else. Resulting in them growing up without money and other things. Both get mistreated by the person that switched their lives. And the main character finds there true self and making their way back into their original families.
but through hardship. They are alot of recommendations for this but just gave the one I just finished.
