Noona and her BIG little Bro

Saetbyeol, an office worker who her colleagues love for her small and cute appearance! I’m a bit worried about her because she looks exhausted lately…  “Saetbyeol, you seem exhausted these days.”  “Yeah, because I was playing with my little brother.”  “Really? You have a little brother?”  “Yes. He’s cute.”  “Wow~ He’s really…” Huh?!! Her little brother in the picture is a huge black man?! And this ugly figure is definitely… what the fuck?!
