It's not easy being Ho Goo, a low-key guy who can neither score a date nor score high enough on his civil service exams, which he's failed 7 years running. But when he has a chance reunion with national swimming champion Do Hee, the most popular girl of his high school, his luck begins to change — perhaps for the worse. After staying out all night with Do Hee, Ho Goo experiences a rude awakening when he realizes that not only has Do Hee left him, she's also pregnant!
