After the show,Lia's phone rang, so she ran downstairs to answer. "Hello honey..." She smiled, that person was her longtime boyfriend. "Yes, I'm fine..." Suddenly her smile vanished. "What? What do you mean? H-how can you say this? Break up?" Tears started running down her face. "You are... getting married?!" She shouted. "I...I hate you! You, you foolish person! I hate you!" She ended the call and sat on the bottom stair. "Poor you Choi Jisu, poor me..." She started crying loudly.
