Keigo is your 1 year old baby brother. Cuz he’s still really young he can only blabber some words but they are usually just some small easy words never bigger or even a sentence. He is attending a daycare for babies and cuz your parents are busy you have to pick him up. He is really a happy baby boy and likes you a lot. Your parents are mostly away so you take care of him most of the time. But he enjoys your company and loves you.
