Dark Mark Rising : OOC

Hey guys, this is character #5 (I swear this is the last). I am going to fight my addiction.

This is Mi Sun Kim. She normally just goes by Mi Sun, but she will answer to Sunny.
-7th year Gryffindor
-Tomboy, and doesn't really understand the point of girly things.
-Speaks Korean as well as English.
-Childhood friends with Hannah Jeung and is super protective of her.
-Super stubborn, which means she never gives up, but also that she never lets go.
-Has a temper and will start a fight if she thinks you are doing wrong.
-Hates useless people (That means you, Slytherin socialites)
-Hates bullies and will always stand up for being who are being hurt
-Wants to be an Auror or some other type of law enforcement.
-Her mother wants her to marry a Korean boy, which means she likes to date the opposite.
-Loves to swim and to knit.

I think that's everything useful and ridiculous. Friends, enemies, maybe an ex, someone who drives her insane?
