ARMED DETECTIVE AGENCY

You are working as a armed Detective Agency organization from Yokohama, You got very tired and exhausted so you take a nap, you didn't realize that you got sleep for hours, so when you wake up, everyone is gone on office, There was a note on Kunikida's table that says:

"Hey sorry hehe~ we're all in the mission we're trying to wake you up but you didn't, we're in a hurry." From Dazai

They also left the electricity still turning ON maybe they really in a hurry? You check the time it's 7:03 PM what should you do?
