Glad you enjoyed it. I wish I could watch it for the first time all over again, I love it that much. I think the new season starts next month and it cannot come soon enough.
That first episode really showed how much can arise from something so simple and really sets the tone for the show. Just wait until episode 5 or 6, I won't say anything more, but it is so damn good in every way. Episode 9 or 10 has one moment that absolutely blew me away, I had a feeling something was coming and even then, no amount of suspicion could have prepared me for what was demonstrated. The level of intelligence, observance and deduction in such a short period of time is astounding.
Min Seo, the auctioneer, was the one that I didn't much like. She uses a degree of conniving that I didn't appreciate at all. While Sang Min has a similar approach, it's not the only tool in his arsenal by any stretch, and given that he is very charismatic he doesn't rub me the wrong way at all the opposite, in fact.
