Let me first start this by saying that It's not love at first sight. It's definitely not. I hate everything about him the moment I saw him. God, I can still remember horrible his hair was. It was sticking out to all directions and he definitely looks like some thug at the street. He drinks and smokes a lot. I bet he doesn't take a bath that often too. And his clothes? Don't make me say it please. He looks like a gangster who's ready to rob a bank. 

Jongin and Momo have been friends for a long time. When Momo left without saying goodbye, Jongin is devastated. Now that they are both Idols, It's not easy to be "best friends" again.
