I tried watching this slow moving show but only made it to episode 7. The female lead, Ko Mun-Yeong, is obnoxious, manipulative, mean and all around unlikable. Male lead, Moon Gang-Tae, just takes her abuse so it's hard to respect him. Another abusive bully is his brother, Sang-Tae, whose abuse he also takes. I found myself very frustrated at his passivity, how he wouldn't stand up for himself. Also, I can't really see where mental illness is represented except as a backdrop. I don't understand the hype and high rating. I do not recommend.
