They have the coldest appearance. They never show their other side in front of the enemy. What is always the same is the cold poker face. But when the two met for the first time, they broke their hidden feelings and seemed to open the way for each other - when he talked to her, she felt disgusted, but in her heart she was thinking of warmth. Although he warned her that being with him would have no results, she said that they both had a mission, and even if they were together, there would be no results, and she believed it. However, it was him who melted her. In her world, she thought that there was only her brother and herself or her mother who had been sleeping in the hospital bed, and there was no one else. But he helped her get out of her own world, even if he didn't want to care about her - when he melted her, she was happy, and when she loved him, she was painful and sad; when he was melted, he was happy, and when he loved her, although his heart was equally broken, he did not give up... If the time went back two years ago, maybe there would be no such pain today...
