Featuring the ever popular Cha Tae Hyun, Yoo Dong Geun and the beautiful Son Yejin. The plot follows On Tae-il, a super problem child. He has an incredible IQ of 148, but, unfortunately, he's only interested in marrying his first love Il-mae. When Tae-il demands marriage with Il-mae and strays farther away from school, Young-dal and Il-mae come up with a proposal to 'bring Tae-il back to the right track.' He openly declares that he would allow Tae-il to marry his daughter Il-mae if he could raise his rank up to top 3, 000 nationwide from his current status of 300,000. Tae-il accepts the ridiculous proposal without a second thought. And 2 years later, he does pull up his rank up top 3,000 nationwide and is admitted to the Law School of Seoul National University. However, fooled by Young-dal's skillfully touching(?) performance, incorporating tears and snots, Tae-il gets softhearted and promises Young-dal that he'll keep Il-mae 'pure' until he passes the judicial examination. A man's words weigh and worth as much as thousand gold! From then on, Tae-il's ultimate mission is to protect Il-mae from all the sleazeballs who approach her.
