B.K. means
Kira and Bento. They are teenage couple who met when they were 11 and 13 years old. It was
love from the first look. They had long distance relationship. They've been through a lot together, but they
never gave up, because it’s even not just the real
love, they have something that universe couldn’t make. They always saved each other and cared about each other more than anything. They are the most important for each other. And we know, we are sure now and here, that together, they are incredible and more powerful than whole energy of universe.
