She loves Himari as her friend because they've been childhood friends since the minute they met as infants. Himari was a very good girl because she loves it when Noriko takes care of children, especially babies because Himari got excited too easily, after class she received a message from her mother, Chiyoko on her phone that says, "I'm going on a business trip for one week, so, your uncle is staying at your house for one week, but don't worry, your cousins are there." Her eyes sparkled in excitement that she ran home and got home quickly. What happens next?
