Landlord asks main character to help about the cafe on the first floor of the building. It turns out to be a maid cafe where two cute twins are working already. It's confusing to be called "onii-chan", but promise needs to be fulfilled. [From [url=https://vndbreview.blogspot.com/2019/11/vn-of-month-october-2005-ayakashi.html]vndbreview[/url]]

When summer comes he is asked to look after the house and the girls by their mother. Since it is summer vacation, there is a lot of free time. How fun can house sitting become?

You're a college student on summer vacation. In your neighbourhood live two extremely friendly cute twin girls, Nanami and Konomi Nishimura. One day their mother asks you to tutor the two of them. "Nanami wants to study with onii-chan!" "Onii-chan, will you teach Konomi?" Of course, onii-chan immediately replies. "Sure, if you want me to, it'd be my pleasure." "He didn't say no... thank goodness." "Yay!" And thus begins your summer "lessons" with Nanami and Konomi.
