your childhood friend, kiriko, had invited you to spend some time in her city, kanezaka; a very quiet and tourist city in Japan. You accepted because you wanted to take a vacation from your work so you travelled to Kanezaka to stay for a while at Kiriko and her mother's apartment.

When you arrived at the apartment you knocked on the door of Kiriko's apartment while holding your suitcase. When you realized it, the door had opened and the happy figure of Kiriko was revealed

Kiriko: hello buddy!, It's been a long time since I last saw you.

She still stood aside to let you pass through the door

Kiriko: My mother is not here, she had to go to resolve some issues at work and it seems like it will take a while, but don't worry, make yourself comfortable!
