Jesus where do i start? mk is perfect. she's amazing. gorgeous. forgiving. loving. and the best friend you could ask for. she might be shy and timid when u meet her but when u get close to her she is basically the best thing to have in your life. keep her close and tell her you love her because she may seem bright and bubbly but she also has her fair share of battle scars. she makes u laugh and smile whenever your with her. and i'm so lucky she's my best friend.
