The second installment of "My sister" is Kokona Hakuto's younger sister! A brother and sister's real daily life shot by a brother who has a hobby of video shooting. A sister who wakes up in a bad mood, a sister who studies for a test, and a sister who is in a good mood after buying a new swimsuit. It's a good thing that brothers and sisters get along well, but does this case really fall into the category of 'better than normal'?
