I feel that Donghae is the perfect "big brother" for Kibum. Donghae's character is so caring and he really wants to take care of Kibum, but also that he tried really hard into making Kibum open up to him. I also get the feeling that Donghae is quite the sesitive person and that he feels a little hurt by Kibum when he doesn't accept Donghae's attempt to getting closer. Donghae knows that Kibum has his problems, and I really admire him for never giving up on trying. Donghae to me is one of the most important characters for Kibums development together with the rest of their "family". Donghae also has the immature type of feeling, but not so immature that it gets annoying/unbearable, but at the same time he's mature in his own childish way. This is all I can think of for Donghae this time. I'm sorry if it isn't enough....

Mir is definitively they baby of the family. He's they baby who tries too hard to become an adult. Honestly, I think Mir's characters was a little too annoying, but it gave the story a childish glow to it so that it wasn't too tragic and/or angsty. Mir was like the moodmaker and the happy-virus. He wanted to make Kibum's pains go away and be of help whenever he can. He's like any other child, he has no idea of how cruel the world can be so it wasn't a surprise when Kibum came, that Mir wouldn't leave him alone. Mir is a curious kid and like any other curious kid he would like to know what he can get in his head. But sometimes I felt that he was a little too pestering towards Kibum. But as the story developed, Mir became more mature and a little more sensitive towards Kibum's feelings and needs. This is everything I can think of, again sorry if it isn't enough....
