You were watching a new uploaded episode of season 4 of Bungou Stray Dogs. Tecchou and Jouno was in the scene. Jouno was complaining at Tecchou in the scene.

Jouno: I've been certainly hating you the most.

Tecchou: Hate? Why?

Jouno: Because your soul is entirely lacking in artistry!

Tecchou looks at you through the screen.

Tecchou: Am I?

Wait... That scene doesn't count in the manga nor in the show...

Jouno glares at him from behind

Jouno: Tecchou-san! You're breaking the 4th wall again!
