What starts as a flashback set in 1995 to 2000s , with Korean Economy being bad and everyone struggling financially, we have Na Hee Do ( Main Heroine ) wanting to become a Fencing champion and we have Baek Yi Jin ( Main Hero ) wanting to solve financial crisis for family. Na Hee Do and Baek Yi Jin eventually fall in love, but in the end they separate because their jobs keeps them busy and they don't have time for each other. This drama is good, but it could've been much better. Na Hee Do in the present ( 2020 ) doesn't meet Baek Yi Jin , which was disappointing. It is a good high school romance story set in the past. We also have Ko Yu Rim ( 2nd Heroine ) , also fencing champion fall in love with Moon Ji Woong ( 2nd Hero ), and their romance, chemistry is much better than main Hero , Heroine. This journey is growth of these characters over the years, but it would've been better if it was set at high school only. The show could've been much better if it had incorporated elements from 1990s but still a good watch
