Mushy Rice Omelette
At the Oshimizu household, Nako is taking care of most of the chores, from taking care of the children to cooking. She is even reliable for the parents. Even though she lives like this, she is very shy when outside, not wishing to go "above the water", as she is afraid of not being able "to breathe". The next pay day, everyone receives their usual wages, while Ohana's is decreased because she broke a vase in the meantime. On the other hand, Nako's wage has be raised. Even though she receives this much, she plans to save the money instead of spending.
Later in the day, at school, Yuina listens to what Ohana, Minko and Nako will use their pay for, but is unhappy by the fact that they decided to use them for dull reasons. Especially for Nako's sake, Yuina invites everyone to go out shopping. After school, the four goes out and shops, but during the time, Nako is being picked upon by a group of men who are asking her out. As she is not used to this, she runs away, along with the other three.
The next day, knowing that the shopping the day before would not help her change her shy self, Nako goes to work and tries to be how she is at home. Even though it works out at the start, Nako accidentally ruins the filming by one of the customers. Nako apologizes to the Madam Mistress, thereafter asking why she received the raise. The Madam tells her that she received the raise not so she would know she has to improve, but because she received lots of good compliments from the customers. She tells her that Nako at the inn, is her self as a waitress and that Nako doesn't have to change herself.
