Not similar concept but both are office dramas. The humour is kind of similar and they game me the same vibe honestly.

Both of them are thrillers with comedy. The stories are definitely not similar but (atleast to me) the comedy pretty much is.

Both have them are pretty similar. The kid in wonderful life is the only addition.
The story about the ml and sfl and fl and sml are literally the same. If you liked one you'll enjoy the other

They both have one case per ep kind of format. Also the leads in both the dramas can see ghosts

Difference:
While May I help you is romance based Missing: the other side isn't
But both the dramas are heart touching and worth watching nonetheless.

Both the shows have ML falling for the FL who is a single mother.The interactions of MLs and babies is soo cute?
