Hide and Seek (2018)

Kind of same vibes, slow-paced drama. Both FL are mistreated physically and mentally. In Hide and Seek, there's an enemy to lovers relationship and although the romance is not the main plot of the drama, it's still present.

both the grandmothers adopt a littlegirl to save their precious granddaughter and this combines the fate of the girls.

Similar plot the heir disappears family raises adoptive daughter real heir raised by other family then family is reunited then the fallout from there. Lee Yoo Ri plays the same role of the apodtive heir this time she not as not by choice

There are relatives in the female leads' families that would do anything to get rid of the female lead. In Hide and Seek it is her Grandmother and in Inheritance, it is her mother-in-law. The difference is that in Hide and Seek, the female lead has backbone from the beginning. While the female lead in AHYI, grows to have a backbone later on.

The vibes of this show are similar. Other similarities include:

1. Song Chang Eui is the male lead in both
2. Both have an adopted daughter helping with the family business while under the threat of a long lost step-sister
3. Forced marriages, betrayal and intense makjang

Highly recommend both!

Sunny Again Tomorrow is very lighthearted compared to Hide and Seek.
However, they have very similar premises.
Sunny Again Tomorrow is about the famous CEO of a fashion brand searching for her daughter for 20 years. Meanwhile, her daughter has been raised in another family and has opened her own small clothing shop. The niece of the CEO actually saw the daughter get kidnapped on the day that she disappeared, but she was young and scared so she never told anyone. The daughter falls in love with an office worker, invoking the jealousy of the CEO's niece (the niece has a crush on the ML) who eventually finds out the true identity of the daughter and tries to cover the truth.
Hide and Seek is about two women. As young girls, they exchanged their luck (one was unlucky and the other had good luck, and a shaman exchanged their fates). The two girls do not know each other at all. The girl who took all the bad luck grows up normally while the girl who took all of the luck disappears. the lucky girl's mother who is the CEO of a fashion company desperately searches for her and crosses paths with the unlucky girl.

Fake adopted daughter,missing biological daughter,fake daughter who want love from her mother.. lots of similarities.
