I won't say both dramas are similar bcoz this is more on comedy side. This is "an intriguing story" of finding the real dad.

- all 3 couples in it have a contract/fake relationship
- includes corporate/ business stories
- one couple (ceo x actress couple) has a close bickering relationship
- includes gangsters, beach shots, nightclubs, typical lakorn stuffs

Both dramas have a similar way of keeping you guessing on who the female lead will wind up with in the end. I think Reply 1997 does it better though.

Both females have a physical insecurity and the male lead is there to help them heal by being their coach/doctor. And who falls in love with them, insecurities and all.

Both dramas are similar as they highlight the difference an adult's influence can make in a child's behaviour and upbringing, although the nature of relationships shown in the two are different. Both feature strong female characters who will do anything for their respective children, and kind caring teachers who work with the main characters to get to the bottom of the mystery.

Both are set upon cold cases. Both are very emotional and great OSTs especially in Cold Case: Shinjitsu no Tobira.

Both drama are based on the story of two best friends who are drifted a part from each other because of their family then reunite again after a lot of hardships and enduring journey ,,, Both drama have strong emotional bond between the two leads and a lot of sad very melodramatic stories ,,, Both are similar in so many ways despite the fact that this was a Korean drama based on true historic events and the other is Chinese based on a BL novel ... I recommend the Korean version so much after watching the untamed

It's another cast of celebrities that are taking on the opening of a business, except this time it's a surf shop! They will manage the shop, taking on the costs and responsibilities of opening a business. Very similar to fourtry!

Both of these dramas also use the plot device of reincarnation.
Both of these dramas have the same FL. And both have very good bromance.
Both of these are also very comedic while being mysterious at the same time.

Although these dramas do not have similar premises, they do have one similar plot device. Both of the couples in these dramas knew each other in their past lives, and the FL's both died because of the ML's.

Both of these dramas focus on a beautiful couple (with the added bonus of the same actress playing the FL) who are facing hardships because of their secret past.

Beautiful World is about the issues of jealousy, bad parenting, sexual assault, and school violence.

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.
