Five years ago, when they were in their prime, when they first met him, she kept her gaze on him and never moved away. It seems to have become a habit to look at him silently from behind, but he ignores the scenery behind him. Unknowingly, five years later, we met again.

She has never regretted crying for him or hurting him. When I knew I had to let go, I discovered that there was a beautiful scenery behind me. .
