"Jin Hua began cleaning while in a cold sweat but Ham So Won continued to lecture him..."

That continued lecturing is just nasty behaviour. That's what really kills a relationship. You have something to complain about, say it once. When your partner starts fixing the issue, stop complaining. Don't be an ass by treating your partner like a child. It makes it look like you get pleasure out of making another feel bad, like a bully.

Personal relationships, especially marriages, should not be played out on a television show. Two things I have noticed; "reality" tv creates, and nurtures bad behaviour, all to keep interest and money coming in. Who suffers at the end....the couple and their children. Your private life should not be fodder for the entertainment of others who do not give a damn about you.
