Well, you are in luck as these guys are rather big on 'daddy issues'. ;P They do have real reasons for them issues though.

Thinking back, I feel that the story is just as much about the guys and their relationship as it is about the girl. And they do have more in common than just her as well (something that gets revealed pretty early on). It's a very bumpy relationship considering they really have to learn to get along and co-operate. There's quite a bit of jealousy that has nothing to do with the girl either. I found the undercurrents below the fun parts, the romance and 'your normal k-drama angst' interesting.

What I liked as well was that there were no crazy characters, they were all more or less normal, faulty human beings.
