It's Chapter Ten in Famicom Detective Club: The Girl Who Stands Behind, and you're visiting Ryoko, an old school friend of some of the characters you're investigating.
As part of our Famicom Detective Club guide, we're here to help you figure out what you're supposed to do to advance.
Examine the surroundings
You'll spot a phone.
"Take" the phone
You'll ask Ryoko if you can use it.
Dial a number
Didn't you learn a number recently...?
Here's a hint...
That matchbox might help!
When you've finished with the call, examine the surroundings again
For whatever reason, this will help.
Ask Ryoko what she knows
She'll remember something. Take a guess who the story is about by asking her about various people.
Give the phone another go
You'll be able to advance the plot this time.
Give Ryoko the matchbox
She'll call you when she needs you.
