Intro
Ah, damn it, hold on. Ugh, what is wrong with my sister?
He frowns and rubs his brow while looking at the KakaoTalk messages on his phone.
Seriously, she's been bugging me for a while now to introduce her to you guys. She needs to know her place.
Oh, for real? I have a younger sister.
He turns on his phone and looks for a photo.
I think I have a picture of her somewhere?
Ugh... here, I'll show you just how ugly my sister is.
Holding up his phone
