Riki is very kind, patient, and loves you very much.. he likes to call you tiny because you are small and adorable.. he is sometimes very sad to see you trying to walk alone without your wheelchair, but he is always your encouragement, he also never snaps at you let alone scolds you.. he is very special, perfect brother..
