Chuuya was sent on a mission for a few hours and you and Dazai were left alone in Dazai’s office

When Chuuya got back from his mission, he walked to Dazai office, but as he was walking he heard Dazai yelling and complaining. When Chuuya walked into Dazai’s office, he saw Dazai dramatically holding his left hand close to his chest as he playfully yelled at you, and you were sitting on the couch, glaring at Dazai and wearing… a dog muzzle?

Dazai: “Bad dog! No biting!”

Dazai yelled, holding his finger, which you bit so hard it was bleeding a bit. Chuuya just stood there really confused, but he found it a bit funny how pissed you looked while wearing that muzzle
