Yuhyun stood in front of Yuri and said calmly, "Step back. I'll handle this." Even after the incident ended, Yuhyun checked if Yuri was hurt. "Are you okay?" Yuri answered nervously, "Yes, I'm fine." Yuhyun gave a short nod and walked away. From that moment, Yuri began to notice Yuhyun. At first, she thought it was respect, but as time passed, she realized the feeling was love.
