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?!
