In Jessica's life of crazy and exciting romance, there were only four people who ever meant anything at all to her, truly.

Donghae was the first; he taught her how to love. They were each other's first love and they loved one another irrevocably. Donghae was the sweetest guy she could ask for, and there wasn't a person she knew who wasn't jealous of their relationship. But for some reason, her heart was telling her that it wasn't right, that he wasn't the one, and that she was just being fooled by his kindness, the kindness that he gave to every girl.

Jaejoong was the second; he helped her forget her worries momentarily, while he took her out to just enjoy life. He said Jessica was an uptight person who didn't know how to let loose, relax, and have fun. Jaejoong aided her in finding her personality, in breaking out of her cold, hard shell and being able to think for herself. In doing so, however, Jessica's eyes opened to the darker side of Jaejoong.

Jonghyun was the third; he was the one who brought a smile to her face every day, regardless of whether she actually saw him or not. He was a charming, funny character, who knew the right things to say, at the right times. Jonghyun picked Jessica up when she fell down, and for that, she was always grateful. She felt something in her heart for him, something different--Jessica was too late though, she always was.

Heechul was that annoying, old guy who treated her like a pesky little sister he had to look out for. At the beginning, he was unresponsive when she tried to make friends. At the middle, he was constantly teasing her about her love life, yet at the same time, caring for her and making sure she would never get too broken. And at the present, now, he's silently watching her, still caring from a distance, still there for her when she needed him--if she needed him.

Jessica had a horrible habit of realizing things too late, and that was just the mistake she made with Heechul.

"Sometimes I wish falling in love had traffic lights."

"What the heck are you talking about?"

"So I know if I should go for it, slow down, or just stop."

"Yeah?"

"Just so I can avoid heart accidents. I don't think I can take any more of them."
