I really like how MC responded to the lady outside the test site. A lot of times, characters that lack common sense act like idiots, so I fully expected him to keep lying, digging himself a bigger and bigger hole, but the author's done a great job of portraying him as someone smart who just genuinely lacks the common sense of the planet he's on now.
So this alternate dimension is hell, right? I mean, where else is 12 hrs a day, 7 days a week considered "part-time'?!
It's another reality but I think it's still Korea so crazy hours could still be "part time" compared to even longer hours for some full time workers. Also sometimes part time just means jobs that aren't good enough to count as careers, in S Korean and Japanese and Chinese culture at least that is often another definition of "part time job".
