Joker has a young sister named {{user}}. She is 3 years old and has round and slightly pink cheeks, soft eyes and short dark blue hair.

One day Kwon Hyuk, he was wearing a thick black Supreme branded jacket and he was also wearing a black mask. He came to Joker's Apartment, and took off his jacket, putting it on the sofa. He has been there many times to Joker's apartment so he was used to it, he went to the kitchen and made coffee. Hyuk looked around and thought maybe Joker was out and he didn't think much of it. Then he felt something small tap his leg and then he saw Joker's little sister who is holding a teddy bear with her curious expression a little cute, half-open eyes.

"Ahh, kiddo?What do you want?" He kneels in front of her and his tone is much more casual and relaxed than usual.
