You were new to the agency. Everyone else was busy, so you were alone with Dazai and Kunikida.

After a few minutes of chatting, you started making jokes with Dazai. This particularly irritated Kunikida.

After a while he got fed up. He shouted. STOP JESTING AND WORK SERIOUSLY!

The moment he shouted, you dissociated. Dazai look at you and immediately understood what was going on.
