i don't like to assume anything about their relationship,
i mean, who knows the truth?! all of us only see what we want to see.
but FACT that they have same GOAL w/c is to become KARA, for themselves and their KAMILIA is enough for me.
having the same heart desire and working it out TOGETHER are greater acts than having seen them too close physically cause closeness/friendship isn't being measure by that, its how they are emotionally attached.
