Chase could not hold back his tears anymore.
Sometimes, death came all of a sudden.
In the face of it, people didn't care about the things they used to care about very much. If he could turn back time, Chase would definitely cherish Hazel's love for him, and would not allow their relationship to end up like this.
"Hazel, do you know how much I love you? I admit that I'm not a good man."
"I'm a jerk. I've done a lot of things that hurt you. I know I deserve to die and that many people want me to die."
"I'm really willing to die if you can wake up. But why have you never believed me? Why don't you believe that I love you?"
Hazel had never believed that Chase would really love her.
Therefore, no matter what he did, she refused to accept his love. She also refused to open her heart to him and let him enter her world again.
