"I am sorry Soo-Yun, about morning." Mrs Jang said while holding her hand. 


"Don't worry. It doesn't matter." Soo -Yun said reassuringly. 


"But, I know your father's case is very important to you." She trailed. 


"You know I can handle myself mom. It doesn't bother me and I don't need you worrying about me. Okay? I can deal with it." Soo-Yun tried convincing her. "I mean it." She said softly smiling a little. Mrs. Jang nodded her head and sighed sadly. "I just hope Jun will recover soon so I can be able to take care of him properly. But I guess he needs lots of rest." Soo-Yun whispered and started walking away. 


"Soo-Yun! Wait!" Mrs. Jang called after her. "I need to tell you something."
