Lee Taemin is the only child of Lee Heechul and Lee Sohee. Growing up in an influencial household, Taemin has always felt pressured from the expectations he gets from others. Taemin is outspoken and fun, and his endearing personality is what makes him so likeable. 

The second daughter of Jung Yunho and Jung Boa, Krystal is known as the "Ice Princess" due to her cold exterior. Although she always appears uncaring and unconcerned, Krystal has a warm heart and is ironically a very emotional person who often lets her emotions get the best of her. 

The charming cousin of Lee Taemin. Kai is sensitive and thoughtful, but is very much an introvet. He often thinks alone, but finds it hard to express his inner feelings to others. Kai sometimes feels like he lacks his own identity (being overshadowed by his cousin slash best friend and everything).

She might appear innocent and naive but this girl knows what she needs to know. Appearances aside, Sulli is a very kind and sweet girl. What most people might not know about her is that she is incredibly intelligent. (Possessing both beauty and brains, Sulli is every man's ideal girl.)
