"Oppa, mianhae. I love you so much but you can't stay with me. I am going to die soon. Go find another girl who can live with you forever, not like me."

"No! Jaehwa, no! You are going to live with me forever, right?"

"Oppa, ije geumanhae! I can't live long. I just found out that I can only live for 3 months. Or maybe... less."

"But you can undergo a surgery for your brain cancer, right?"

"No. Doctor said that my cancer had reached for the 4th stage. I have no hopes but to die. It's too late for a surgery."

Park Jaehwa, 19 years old. She was a happy, hardworking, talented and cute girl. But she became a pale, hopeless girl when she knew she had cancer. Of course, she cried every single day but she tried her best to be happy and not look sad in front of her boyfriend, Yang Yoseob. Yoseob had always loved her though he knew his girlfriend's dying. He just loved her too much to let her go. He knew he would be a loner when she'd died but it was better than dating any other girls out there, he thought. Even Jaehwa had persuaded him to move on, but he refused to. It was too difficult for him to forget her.
