The Boy Next Door

Mark moves in next door to the twins Jinyoung and Jaebum, and immediately hates them. The feeling is mutual.

"Boys! Are you up?" Their mother yells up the stairs. They answer yes in unison, Jinyoung sliding out of bed in his pajamas and Jaebum scrambling to put more clothes on than just his boxers. "Come down here please!"
They answer that they'll be right down. Jinyoung waits for Jaebum to get ready without really meaning to.
"Awww, how sweet, my little baby brother Jinyoungie waited for me?" Jaebum coos, slapping Jinyoung on the back.
"Yeah, whatever" Jinyoung pushes him away, leading the way through their door, the moment they hit the top of the stairs, they freeze. Hearing voices that don't belong to their mom resonating from the kitchen.
They turn around, trying to creep back to their room but of course, their mother knows them.
"Get down here you two"
Sighing, they slowly taking the steps, it's too early to meet strangers.
"Ah, these are my sons Jaebum and Jinyoung, boys this is Mrs. Tuan, she brought us breakfast"
