Yamada Momoka is your average 16 year old girl. Her family consists of herself, her dad who works at a TV station, and her mom. Apparently she also has a strict prune of a grandma, but who doesn’t? Except that the grandma, Yamada Tamaki, had an accident at the TV station where she got electrocuted and now looks like a 16 year old yamato nadeshiko. It isn’t easy for Momoka when her grandma arbitrarily decides to attend Momoka’s high school as a student as well. Tamaki isn’t just pretty, she’s also very cultured, well-mannered, and still maintains her old-fashioned streak from her 65 years of wisdom. It’s bad enough when Momoka starts being referred to as “Old Yamada” and her grandma (Tamaki) referred to as “New Yamada”, it’s even worse when Momoka’s crush on this dashing young man starts to take an interest in Tamaki as well. Fight-o, Momoka! Protect your beloved grandma, Momoka! And don’t let her walk off with your boytoy, Momoka!

Rin is tomboyish 14-year-old who lives with her grandpa in a small village out in the countryside. After her grandpa's death, Rin is obligated to leave her village to live with her mother in Tokyo. When she arrives, she discovers an amazing secret: her mother is not an office lady, but a famous model called Myu Suzuki!
After one night of reunion, Rin's mother leaves to follow some guy to some foreign country without any notice other than a letter. Without any money to survive on (her mom did not know grandpa died), and the contract between Myu and the model company, what is Rin is to do?
