Saetbyeol, an office worker who is loved by her colleagues for her small and cute appearance! I'm a bit worried about her because she looks very tired 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?!
