Choi Sooyoung. The tall, beautiful girl with short brown hair and extremely hot legs is the perfect dream girl for every boy. Her charming looks and gentle personality can make her the knight in shining armor for every girl's fantasy. She's a great catch. She's smart, a straight A student, and a black-belter in Taekwondo. Though some people may think her world is perfect but for Sooyoung her world is still missing a piece. One more piece and everything will be complete. And a certain blond girl with a cold aura can make that happen. 

Jessica Jung. She's popular. She's what every boy in her school wants to go on a date with but never in a relationship with. Every girl blushes furiously when she passes by. She's the school's idol and everyone admires her. She could be perfect if it weren't for her cold and icy personality. She has this signature glare that sends shivers down the spine and an attitude that gives death to every soul. But this winter-like aura of her's will be shattered into smitherins when a certain brunette comes into her life and finally releases the warm and tender personality she always has. 

Im Yoona. Known for being responsible, hardworking and disciplined, this girl is without a doubt the perfect fit for being her school's president. In everybody's eyes, she's the girl who's on the top of her class, always recites and gets perfect scores in every test she takes. Everyone looks at her that way, everyone except a certain tan girl. After seeing Yoona at an abandoned dance studio,  she knows Yoona's not what everyone says she is. More than an honor student. More than the school's president. More like "a spectacular laserlight; perfect in the light and in the dark". 

Kwon Yuri. A tan girl with a mind full of colors and imagination. She brightens everyone's mood up. She has this smile that melts every girl's heart. A personality that gives off the sense of protection, safety and happiness. When someone's in need, she doesn't hesitate to help them. She's selfless and puts friends and family before her. She's like a hero but there's one thing that's missing. One thing, a very important one: Love. She's afraid of it. She despises it. For her, love is nothing but a waste of time - seeing that it didn't work out with her parents. But someone made her change her mind - a "laserlight" - and made her give love a chance.
