Ten years ago, she was kidnapped and he rescued her. They agreed that if they could meet again in ten years, they would be together.
Ten years later, she left the protection of her family in order to find him. However, he already has a girlfriend.
They are like the flowers of the other side but not. At least they can meet each other... When the flowers on the other side fell, she only had one sentence left: Shadow, please allow me to love you in heaven...
A momentary brush with each other, a lifetime of regret.
