Mr. Bo, Please Stop Being Cruel, Miss Su Has Entered the Crematorium.

Su Ruan has been Bo Yunchu's underground lover for three years. She thought that if she stayed with him for a long time, one day, he would have a place in his heart that belonged to her. But in the end, he said that she was just a humble substitute. Su Ruan smiled miserably and left quietly, allowing him to love others. Bo Yunchu regretted it. He found her who was terminally ill and bit her lip with red eyes. "Su Ruan, who allowed you to leave me?"
