My First Diet? Episode 9

As Kana is shocked to find she has gained weight, Yume, Yuuki and Hinata decide to help put her on a day. Hinata gives Kana a dog costume so she can sweat more during her rounds, but she soon gets in trouble with a dog called Jon. After being rescued by Mika, they run into Jon's owner, Sacchan, a friend of Kana's, who asks them to look after him for the day while her family are away. With help from Yume, Yuuki and Hinata, Kana and Mika take Jon to the park, where Mika manages to get over her initial hesitation. Mika tells Kana about how she used to have a dog, but had to leave her behind when she moved. After returning Jon to his owners, Mika feels a bit lonely but feels happy in the knowledge that her old dog is being treated the same way. Kana, however, ends up completely forgetting about her diet.
