Chanyeol, Jinri, Sehun and Joohyun have been friends even since in their mom's womb.

And they call themself as "Fantastic Four"

Park Chanyeol, a handsome guy who having a tall body that makes a lot of girls crazy over him. Since a little, he is famous as a big ear kid and his friends always mock him because of his big ear. but he have a hero, that Choi Jinri who will always protect him from those brats. Chanyeol always feel safe whenever he is with Jinri also two of his friends Sehun and Joohyun. Chanyeol is a man who very talkactive, since he grow up slowly he change become a tough man and bubbly. He have gain a lot of friends, join in band campus, also he is quite smart at his major, that's why a lot of girls crazy over him though. Moreover Chanyeol is a kind heart one, his priority is his friends (Jinri, Sehun, Joohyun). if anything happen to his friends, he will come first than others. Because Chanyeol said he love his friends as much as he love himself.

Choi Jinri, she is almost as talkactive as Chanyeol. She is Chanyeol girl version. She talk a lot moreover if she already meet Chanyeol, they will talk about many things that out of their mouth. Jinri is quite nice but she doesn't trust people easily, also she is a naive girl. she never have been in relationship since she was born, totally different with Chanyeol who almost change a girlfriend every year. That's why Chanyeol and Jinri just like Tom & Jerry who will mock each other yet need each other.

Oh Sehun, a cold guy but the crazy one among his friends (Jinri, Chanyeol, Joohyun). Not like Chanyeol who accept the girl who want to date him, Sehun more like to reject them nicely because actually he have a crush to someone that nobody knows who is that lucky girl. Sehun not really talking much, he prefer listening to his friends than talking. Chanyeol and Sehun are totally different.

Bae Joohyun, shy girl and nice one. among her friends, she acting like a mother who take care of her childrens. Joohyun is mature one, she always watch for Jinri, Chanyeol and Sehun foods. If the kids start eating carelessly she will nagging, yes Joohyun is not someone who is talkactive. She is quite silent moreover if she is in campus, but no one knows if Joohyun can nagging as much as Jinri if she knows Chanyeol, Jinri and Sehun doesn't eat well.
