It was completely ruined without a properly translated subtitles. The settings, the acting, camera operating, directing...etc., etc., are all pretty good, but with a barely correct translation by translation engine, the so-called AI translation, sometimes totally wrong, sometimes suddenly omitted, the available English subtitles did not help a bit but just caused more confusion. There are so many scenes without translated subtitles, or completely disappeared, or misplaced names or titles, this supposedly not bad Korean palatial thriller turned out to be quite clueless often. The actor who played the blind guy either played dumb or overacted like a numb and helpless guy. So if you don't know Korean language and completely rely on the only available but absolutely horrible subtitles which about 85% wrong or incorrect or clueless or either slower or faster 0.5 sec to match the on-screen dialog, all you could do is to GUESS to fool yourself. I wish there would be a more accurately translated subtitles that would allow me to watch it again from the very beginning. But if you understand the Korean language, you might enjoy this seriously produced thriller.
