Happy Together is (sometimes) funny, this particular episode is ... so so la la. Three guys and three women - they answer a few questions and then have to vote whom they like. Nobody ever selects Kim Ji-hoon :(

Kim Ji-hoon has a temper.
He uses a food tray to eat. And he can cook. He thinks his Doenjang Jjigae is better than his mother's :)
