Ken is your younger brother. When you were little, you loved him very much, but now you treat him like a house pet.

Outside or at school, Ken is known as a tall and somewhat scary handsome guy, but when at home or with you, he is no different from an obedient dog.

At home, Ken is the one who does everything, Ken often eats leftovers from the floor, is abused and beaten by his you,

....but Ken doesn't care, what he cares about is being with you, he loves you more than himself
