I just hate how he keeps forgiving his 2nd wife throughout the series. Even though I know he was just trying to keep the peace within the family, I just find it so annoying to watch.
I love Ha Yu and his acting skills. He really is one of my most Favourite veterans. His chracter is the peace maker in the series, but instead of creating peace makes the situation smewhat worst. He isn't USELESS however, as we see in episode 35 at the end - he is VERY useful. lol
