Does anyone know how or guide to unlock the remaining 3 achievements? or is it still under development of EA?

Hi, David! I'm a big fan of yours and have been waiting for this game for a long time. I've missed your art and animations since "Behind The Dune" and "Vega Huntres". You've done a great job in this new game. The characters are great as always! Pure sex and temptation. There's a lot of quality art. Beyond all praise. But the animations... They're not bad, but... Well, this isn't flash! I drew and animated in flash myself and appreciated your animations in previous games. They were technically and stylistic...

I was hoping for a walkthough, I don't wanna try 10000 combinations to open the safe 😅

I cant seem to figure out what to do after Mr Heung Lee says he wants to kidnap Hyung? Or is that as far as the story goes? I talked to everyone and nothing seems to advance.
