“You are by far the most experienced fencer when it comes to losing. Those losses were blocks to build yourself stairs leading up. Think about it. Now you’ve got the highest staircase. Take your time to climb it and take whatever you want.” – Back Yijin

Let’s do our best. But I still hope that even if we fail, we’ll be strong enough to get back up again.” – Back Yijin
“It’s not a failure, but a hardship.” – Back Yijin

- “I know how much your growing pains hurt. I understand.” – Back Yijin
“Sometimes, saying that we can do something can be more discouraging. We haven’t learned about a world in which you don’t have to do well and can fail. Still, let’s do the most we can. Let’s do our best. But I still hope that even if we fail, we’ll be strong enough to get back up again.” – Back Yijin

- “When you try hard, it makes me want to try hard, too. When you accomplish something, it makes me want to accomplish something. You make other people do well, not just yourself.” – Back Yijin
- “I’m going to give my all tomorrow. But you’re not the reason why I’m going to give my all. I’ll give it my all for myself. Because only I know how hard I’ve tried.” – Na Heedo

- “No one gives her stress other than herself.” – Mrs. Kim
- “The only thing I believe that will be constant in this world is gravity. I don’t believe in anything to stay the same forever.

- “Live as an achor who leads by example for society. You don’t do that for your family anyway.” – Na Heedo
- “You never once came to watch me compete. Whenever I came home alone, upset after losing a match, you weren’t the one who comforted me. It was that comic book.” – Na Heedo
“That’s what I like about you. You don’t hide your tears.” – Back Yijin
