Jang Geun Seok does a great job portraying a teen dad. In America we see a lot of movies about teen moms...there is even a reality tv show about teen moms. We never see anything about teen dads. Actually I take that back, there is one made for tv movie about a teen dad that was really good, but not as good as this one. The struggle he has to take care of his child is really well done and there are some great funny parts. Kim Byeol steels the show with her quirky smart character. I really loved that she made #1 in class over that jerk of a kid in her class. It is a really good story that ends well. I recomend everyone watch it.
