In an archaeological exploration accident five years ago, three people died and one was injured. She lost her loved ones and was burdened with guilt. It was also five years ago that she met him for the first time. He was covered in injuries and looked at a certain place on the mountain and cried his heart out. Five years later, when she met him again, he looked calm and smiled warmly. It seems like everything five years ago was just a forgotten nightmare. In life, if you can meet someone who can hug you for warmth in the cold wind and walk hand in hand in the dark night, please don't give up easily.
