Historia
A year has passed since "Okawari" and the 3 sisters have grown up. Their likings and mods are almost the same, Haruka the older sister is a love-giving mother to the younger sisters, but she's also a discipline follower, Kana the middle one leaves everything to the last possible moment and always gives trouble to this trio, and Chiaki the little one is the calculating and manipulating one, she likes to be admired and loved by Haruka and always gives trouble to the less blessed Kana. An unbalanced family, but besides of that they love each other with their whole heart.
