Kaoru
Kaoru, though he will never admit it, hates being half of a whole. He imagines this must be what it felt like for colonies in the past. Never truly independent, and only given a false impression of freedom. Late at night, when Hikaru is asleep, Kaoru yearns for his own bed, his own room, his own life. Kaoru loves being half of a whole, and he never hesitates to proclaim it. He imagines it must be how a colony feels like. Always having someone to rely on, and never truly being alone. At night, his brother's presence at his side, is a comfort like no other.
