Ba Woo my love, you wouldn't confess or kiss him out of pity so why assume that he would do it? Ba Woo is acting like he doesn't know this man better than anyone on earth.
They always say we should respect old people, but this old man is about to catch these hands if he doesn't back off. In fact he deserves a punch for all this.
One thing I adore about this show is that misunderstandings don't last for over an episode. and the fact that they both think alike when it comes to sacrificing themselves for the other.
