The dramas have similar humor and a cute couple even though the guys in Boy Next Door are not together.

Very similar drama: 3 main characters, 1 is a devoted mother, 1 is young and lost in life, there's a cheating scandal, some entrepreneurship, an insight into a rural Chinese hometown
Nothing But Thirty is my favorite of all CDramas ever made, and To Dear Myself is the most similar drama that I've found

Twin sisters
Impersonation
Accident
Male lead gets confused with identity and then tries to keep it a secret

Geu Roo and Jin Tae are both special kids who have to get used to new circumstances due to sudden changes in their lives. Sang Goo and Jo Ha both have boxer backgrounds. They are both cold and rude at first but change while they are learning to take care of someone else besides themselves.

Both productions are set in the same "universe" with Guan Hong Feng (ML in Day and Night) being a supporting/guest character in Reborn.

Lives of male leads in both productions get changed due to movies during the tumultuous period in communist China.

Both productions star Zhang Yi as ML who befriends a teenage girl he once had an enemy-like relationship with.

Similar premise - in Don't Touch Me, Your Majesty ML time travels and has to cross-dress as a concubine, while in Nobleman Ryu's Wedding ML has to cross-dress and become a stand-in for his sister. Both have extremely low budgets, but Don't Touch Me, Your Majesty is a parody, while Nobleman Ryu's Wedding is (slightly) more serious.

Have a similar formula.

The difference is that Ninkyo Helper take place in a nursing home while Yoiko no Mikata take place in a Kindergarten.

Chan's Room is also a kinda show like stay fm where Bang Chan talks to Stay about pretty much anything :))

In both dramas ML is a team member of fire fighting and rescue team and FL is a doctor. Both dramas are having close plot backgrounds.

Both the ML are saving the FL all the time.
Both the FL can call the ML whenever they want.
Both the FL were supposed to die but saved by ML

-female lead change her identity from ugly to pretty
-male lead is one of the popular in school
-male lead bullies female lead

While move to heaven shows the person and sercumtanses behind a persons death prison playbook shows the sercumtanses and the person behind the jail sentance.

Both deal with predjedus and call out the gaps in modern society reaching beyond what is seen on the surface.

And both deal with bonds, in prison playbook its more about friendship while move to heaven is more about family.

Move to heaven is allot shorter but both are great dramas that will awaken a range of emotions in you.

If you liked MLEM you might like MLH. The story line if different but the kisses in MLH reminded me of MLEM.
