Dongwoo's and Sunggyu's apartment: 

They were lounging around on a Sunday morning, getting ready for tomorrow's class. Their neighbor to the right was making a lot of noise like always. In that apartment lived a little kid and his dad, so why wouldn't it be loud. To thier left were two young adults, and Dongwoo and Sunggyu only knew that because ever time a football game was on they would always scream on the top of their lungs. Dongwoo and Sunggyu deemed themselves as the quietest apartment on their floor. On the contrary, Sunggyu and Dongwoo were the loudest. You could hear the two screaming throughout the whole apartment building about who was going to do the cleaning in the house, shopping for groceries, and deciding on what they were going to eat for the night. The two were, in fact, the louest in the building.

Sungyeol's and Woohyun's apartment:

Same Sunday.

Woohyun was in the kitchen trying to come up with a new recipe for his bakery, while Sungyeol, also in the kitchen, was planning out the agenda for his class. To their right were the loudest neighbors they ever had. They would scream about everything, and even pass 12 a night they would scream. Their neighbor would eventually calm down, but continue to scream ten minutes later. Woohyun would go over and tell them to shut up, but ain't nobody got time for that. 

Hoya's and little Sungjong's apartment:

Same Sunday

Hoya was in the study room doing his work, while Sungjong was in the living room playing Mario Kart, on the Wii. Once in a while Hoya would hear Sungjong yell of excitement because he had just passed a level. It was pretty quiet, until they heard their neighbor, to the left, yell again. Hoya was so close to going up to their door, and punching them, but being a welll respected man, Hoya kept him calm. Instead, he continued to file a warning toward a daycare that was late in paying their rent. 

An overview of the family!
