It was an excellent drama and some people will beg to differ because of the ending but I loved the drama including the ending. If you think of Na Hee Do and Baek Yi Jin as two lovers then this story's ending is not what you'd want but if you think of them as soulmates, the ending will hurt you but not as much because you'll know that no matter where they are, they'll always hold a place in each others' hearts.

The story/plot was well made. It all started with a simple fencer and a bankrupt boy and it went on to talk about life, dreams ,adults, burdens, importance and to portray a relationship where in both lift each other up. The writers sure created a good story with all the crisis, emotions. Na Hee Do isn't a perfect character, she's a great fencer, stands up for herself, optimistic, but at the same time is impulsive and wears her heart on her sleeve.
On the contrast there is Baek Yi Jin, a boy whose family is bankrupt,having a hard time and promises people to never be happy and suffer the consequences of his father's actions. When the 2 worlds collide they create a balance, they cancel out each others' worst traits and give each other what they need - reality checks,hope, courage.
A couple who shares similar dynamics are Ji Woong and Ko Yu Rim. Ko Yu Rim, a gold medal fencer who constantly puts herself down, poor, hardworking but succumbs to pressure and power. For her there's Ji Woong, smart, optimistic and someone who likes her whole heartedly.

If I were to sum up this drama then it's beautiful, simple yet elegant. It'll give you nostalgia of the 90s but also remind you of the problems. It'll teach you important lessons straightforwardly yet it'll give you a good dose of happiness. I've loved this drama and it's definitely worth a watch.
