What I don't like is why blur out certain parts of Cha Seung Won? Well I looked and looked and then I realise the mosaic covers are to cover his tattoos. Seriously? And originally the "son" is played by another actor who was edited out completely from episode 1 of Season 1 because he had a scandal; for not paying tax. And that tax scandal wasn't his fault, probably overlooked and he had fully paid his tax. I don't get the small whiff of scandal and poof, edited out.
Like how they joked in The New Journey To The West; gambling habit is scandal. Fine. Did not pay tax a scandal. Fine. Divorced from wife, also a scandal. Breaking up with girlfriend is also a scandal.
