They look exactly the same, but that was all that was, Kiina and Kania are twins, but have hardly any contact. Kania called Kiina just when she was in trouble, as happened every three months or so, one day calling Kania hysterically from Korea and ask Kiina to come from japan.
 Kiina take the first plane together with his friend Kame (Kamenashi Kazuya). She finds Kania in a shady bar and get into trouble with a couple of guys. Kania runs away and tells Kamethat Kania was not there, she takes over her twin sister's life and returns to Japan with Kame.

Leeteuk find Kiina in an alley and saves her. Her memory is gone and all her stuff is gone. She has to stay in Super Junior, but will they ever find out who she is?
