This is the story about Su Yi and Sun Tianyi.
The story originated from Su Yi having a dream one day. After waking up, Su Yi suddenly understood that no matter how sorry or guilty he was towards Sun Tianyi, if he could not let him know, everything would be nothing.
So Su Yi decided to record it completely.
He thought he would see it.
Although almost ten years have passed, Su Yi still hasn't waited for that sentence, but he thought that maybe one day, at a certain time in the future, he would wait for a phone call, and the person on the other end said, Hey, I forgive you.
