The series isn't necessarily bad (based on the four episodes seen) and the actors are actually pretty good. But it's just lacking chemistry in all sorts of ways and it's hard to pinpoint why. The first episode is nothing like the second episode forward as it takes a leap from somber to an infusion of comedy. I was pretty excited that it had a relatively similar feel to the Fiery Priest in the beginning but it was short-lived. The ML/FL characters were made to be too extreme in personalities from the start and then shifted out of character very quickly and continually, which made what would have given them their individual charm a blur instead. The supporting actors were even more extreme with their personalities/quirks and it took too much realism out of what is actually quite a decent plot.

As some minor examples, the ML is supposed to be a badass high up on the chain in the Italian mafia. Yet when he arrive in Korea, he's easily drugged by a drink offered by a cab driver and then mugged? I mean, even normal tourists with any common sense would have known to not get into a random black car at the airport when the driver is being overly pushy about using their services. As for the FL, while the actress did the best she could with what she was dealt, the character was spicy but didn't make much sense. They should have highlighted more on the reasoning behind why she was working against her father before she suddenly decided to have a change of heart. The tiny explanation of their relationship right before a major event really didn't do much. Then there are the tenants living/working at the building who are supposed to be regular folk but their characters leans more towards a circus-asylum feel. The ML's interaction with them is equally awkward.

Should reiterate that the series isn't necessarily bad but unfortunately dropping the series because I've already seen how well it can be done with the Fiery Priest.
