Since her dad's death since elementary school, Kamura has taken the role
of being the responsible one in the family, including cooking,
cleaning, and simply even getting her mom up for work, whom she promised
to always protect. But then her mom tells her that she is getting
remarried, and finds out about her soon-to-be 2 year older
brother-in-law who she just saw homeless on the streets the day before!
And now her friend Youhei, who always teases and makes her feel like a
fool, is acting differently...and even tries to comfort her?! Will
Kamura be to able accept her new family life with a father and brother,
and be able to let go her feelings of being responsible for her mother?
