Golden Garden (2019)

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.

similar chemistry between the ML and FL where they both start off by fighting (one more than the other).
both stories contain a 'sister' (stepsister/cousin) role that is jealous of the FL and prevents them from being able to find the FL's long lost mother.

- both FLs grew up as orphans and both mothers are villains
- both dramas have hit and run incident in the beginning episodes
- in GG her identity was stolen but in RS she was abandoned, they could've had the chaebol life that the 2nd FL has in their place instead of them

Both are mystery dramas where the FLs lost their memory and stay/help out at the antagonist's household

A greedy overly obsessed scheming and conniving stepmother still's her stepdaughter's life for her own daughter. She does everything in her power to oppress her stepdaughter and to hide the truth.

Both has sisters that are not blood related.
But the difference is My golden life has good sister relationship.
Golden garden has bad sister relationship.
Both dramas are full with secrects and drama.
