Everyone's favorite pretty boy Super Junior member Choi Si Won was born on April 7, 1986. And just like he looks now, he was just as pretty back then.

He then began blossoming into an even prettier boy in middle school.

Choi Si Won didn't let his parents know that he had plans to audition for SM Entertainment. When he passed the audition process, his parents found out and weren't too happy with his choices. It still didn't stop him from taking a bunch of selfies.

Choi Si Won made brief cameos in such dramas like "Precious Family," "Eighteen," "Twenty-Nine," and "Spring Waltz."

Mr. Choi made his singing debut with his 12 other members in "Twins (Knock Out)."
