Sulli's POV   It was another perfect day yet again. I was waiting in the park for Sehun. After waiting for a long time, I got furious and phoned him immediately not able to keep the reputation of being a cool girlfriend.   "Hello?" I said after the call was connected.   "Hi. Who are you to call my oppa first thing in the first thing in the morning?" A woman answered coldly.   "I am his girlfriend! Who are you?" I asked her back in a stern voice.   "Girlfriend, eh? He has a girlfriend?-"   "Who are you?" I asked her again.   "! What are you doing with my phone!" A man shouted in the back.   Just after that, the call was disconnected.   My mind was still in a daze but soon they were filled by many thoughts.   "Who was the woman?" "What is their relationship?" "Was he cheating on me?"   To make everything clear, I decided to dial him.   I opened my phone and went to the call history. I was going to press on his name but I hesitated...   "What if he really is cheating on me? What am I going to do then?" I thought as my hand start to tremble.   All of a sudden, my phone started to vibrate. I looked at the screen and it said," Sehunnie". I started to panic even though I am not the one who is in trouble. I took a deep breath and answered the call.   "Hello?"   "Sulli ya~ I am so sorry....I don't think we will be able to go on a date today....I got some meetings-" once again, he tried to get out of the situation by giving ridiculous reasons.
