KICA-5046: PERSONAII INNOCENT SIN ~THE ERRORS OF THEIR YOUTH

[Phonograph]

where does that chin yang come from?
I watched some character names and I don't see what it can be

[Dag]

情人 (pronounced チンヤン) is used by one of the characters (Chinese culture lover) when talking to the MC.
It's supposed to be Chinese but IDK how that romanization works (the interwebs have "qíng​rén​").

[Phonograph]

I went for "chin yang" ("quing yang", maybe)
blah or another chinese-speaking guy could help

[Dag]

Apparently the US PSP ver. has "chinyan".
While the "yale romanization" is "ching4 yan4".

From here.
