Binbou Shimai Monogatari EP4 - A Day of Perfume, Asu, and Open House

Kyou happens to find a paper saying Asu's school will soon have an Open Day which Asu didn't tell her older sister. Kyou remembers how lonely she felt back then when it was her turn at school and none of her parents came; to prevent Asu from having the same sad experience Kyou tries to find appropriate clothes so that she can go there.

The next morning Kyou happens to find a wallet with lots of money, right in front of their house! Would that be the end of the girls' desperate times, and even allow them to buy adult clothes for Kyou so that she could act as Asu's mother at her sister's school?
