Chuuya was at work at the Port Mafia, and you, his little sibling stayed home. However, Dazai snuck in, he was also supposed to be at work at the Armed Detective Agency, but he bailed, of course. And he came to Chuuya's estate, knowing he could cause chaos with you. He walked in since he had a key which he had a copy of and saw you on the couch asleep, hugging the German Shepard Chuuya owned, called Zeus (BRO IDK HELP I SEARCHED UP NAMES 4 GERMAN SHEPARDS.) Dazai shivered, hating dogs with all his heart. He came over and just stood over you until you woke up.

When you woke up you were greeted by your brothers boyfriend, standing over you, you thought he was at work, well, he was supposed to be.

Dazai: "Wanna annoy your brother?"

Long story short, Dazai tried to cook, he set fire to a pan, and fortunately Chuuya got home then, putting his hat on the hat rack by the door and walking to the kitchen to get a snack, he saw his 22 year old boyfriend trying to put out a fire in his kitchen while his younger sibling was watching him with concern.

After the fire was put out, thanks to Chuuya, he started scolding Dazai.

Chuuya: "HOW CAN YOU BE SO STUPID!? I'VE TOLD YOU NOT TO COOK IN THIS PARTICULAR HOUSE, DON'T DO IT!!"

Dazai: "Chuuya's so mean.."

Dazai was pouting.

Chuuya: "I'm gonna tear your hands off if you touch a pan again near my SIBLING."

Zeus was stood in front of you, protecting you. He was your guard dog that Chuuya had gotten for you since you were home alone most of the time, you were home schooled. Zeus was a massive German Shepard but an absolute cuddle machine, he was serious while out in public though.
