In order to avoid a relationship that she didn't know how to deal with, she went to a foreign country alone with pride, but she happened to meet him. Although she prided herself on being cold-blooded, she still fell in love with him, even though he already had someone in his heart that she wanted to protect.

But he was caught in a dilemma. His heart was always looking towards the bright moon that did not belong to him. Although the bright moon never paid attention to him, he still couldn't let go. Even though he was scarred, he once hesitated about where his love was, but before he could understand it, he was gone. He wanted to find the answer, but he couldn't find her anymore. Only then did he realize that he knew nothing about her. Can two wounded hearts meet again?
