He had been waiting for five years. If it hadn't been for a class reunion, he wouldn't have met her so quickly.
After five years of waiting, he just wanted her heart to be filled with someone else
Five years ago, she didn't know that she had become the person he missed; five years later, she only knew that she didn't want to recall the past, but she didn't know that there was also a person who gave her sunshine in the unbearable memories; in the past five years, she may have forgotten him, but she didn't know that someone was waiting for her there.
He only wants to have one person's heart and never be separated from each other. If there is no love from her, he is willing to protect her silently.
