What Korean only games on PSN I can buy?

[Richtoon 67]

I have bought Survive Mr. Cube and Steins; Gate 0 on my Korean psn account. I have some Korean money left, what else can I buy from Korean PSN store? Games must have KR stackable trophies. 

 

Thanks

not sure if it has a stackable list but I know a game that was made by a Korean game company. it is a called White day. it is on the uk store and us I think as well but yeah I know it might be odd but yeah it is a fun game and you will need to know abit of Korean to do a puzzle in it mostly a number based one. also maths. times of the world and so on.
