Ohana Matsumae is a sixteen-year-old girl with no purpose or direction in life. One day, however, she gets the chance to reinvent herself when her mother and her boyfriend do a moonlight flit to escape his debts. Left alone, Ohana goes to live with her estranged grandmother, but when she arrives she finds herself forced to work at the family’s hot spring resort, the Kissuiso Inn. With her grandmother considering her nothing more than an employee and a roommate who hates her, Ohana’s happy dream of a new life soon turns into a nightmare. Now the wide-eyed girl must learn the value of hard work as she attempts to make friends and familiarise herself with life at the resort.
Though the beginning episodes of both of these series make them seem like dramas, both eventually settle into a more episodic slice-of-life routine. As such, they feel much less fluffy and meaningless than most slice-of-life series. If you liked the feel-good atmosphere or hard-earned friendships in either of these series, you'd probably like the other.
