Kangin is best friends with Leeteuk and others known as Super Junior. His little sister just happens to be Kim Taeyeon, a popular girl at her university for the people she hangs out with and her beauty. Leeteuk has always admired Taeyeon from afar but never made a move, obviously because she's his best friend's little sister. Heck, Kangin would probably explode if he found out! (he's very protective about her... XD) B
