events in both films take place in the baseball world ..........

... from the same writer. Both of them have unique atmosphere and characters.

Both dramas have this old school - but effective - Lois Lane &Clark Kent/Superman relationship between the leads.

Also, the Female Lead is the same in both dramas, so you can see the improvement of the actress.

this drama is also about the main character suffering from D.I.D (multiple personalities)

Both rom-com where the female leads are people from the high society who, for different reasons, became maids :)
Maybe PKK is even more enjoyable because it's shorter... but that's just my opinion! ;)

Similar manic humor with a lot of heart and a great main couple. A more episodic feel, but each mini-arc stayed closer to the show's intended theme and was well paced. Super short.

both dramas about pupils stacked in a place with no connections to outer world, and with a psychological outline

the leads in both befriend a lonely and hurt ghost they can only see.

both drama consist of mostly the juniors of Johnny's Entertainment

the leads in both can see ghosts and ghosts follow them around to relieve their grievances.

ghosts in both films are trying to relieve their grievances though human beings.

the leads in both can see ghosts and ghosts follow them around to relieve their grievances.

Both were written by the same writers (Kizara Izumi, which is a group of two). I'd say Yuube no Curry is a definite spiritual sequel of Suika and incorporates a lot of elements that had been used in the latter (i.e. Obon festival).

the main guys have a similar "hidden identity" and the main girl character is Park Min Young.
