I probably need to justify myself.

IF you know what you're doing,
OR are very careful,
OR try to complete every single meticulous little thing before proceeding (which i did back then)

You won't get softlocked,
you won't run into the issues most complain about,
and instead,
You will have a great time with an enjoyable, cute, funny, somewhat challenging story that just doesn't have many rivals on PSP when it comes to Asian RPG's. Especially not KRPG's to my knowledge.
