"Ok class, the test will start now. Pls give your tests sincerely. " taeyeon said. The class as always has no response to her. Taeyeon sighed. Then she saw the clock that was hanging on the wall. "Ok everyone. You can start your test ." taeyeon announced. The students then started to give test. The whole time they were silenced and giving their tests. Taeyeon could easily see some students frowning over the question. But some not. Tzuyu looked expressionless as ever. It was math exam. Dahyun and yoongi looked chill. But others looked pretty confused. Not to mention taeyeon set the question medium. Not too easy, nor too hard. But the looks on the students face says something else. Like they are seeing some alien language. 'But i didn't set it too hard.' taeyeon thought. The students wrote nevertheless. Answering what they know. Tzuyu's pov: After the hell of tests we are now inside the cafeteria. The section B approached us again. We let them sit with us. I have to say that in those few encounters we became friends. Like genuine friends. Suddenly i felt someone staring at me. I looked around and saw sana staring at me. But she shifted her gaze somewhere else. Weird. I looked at my idiot friends who are literally flirting with their crushes. Excluding seulgi unnie, jihyo unnie, sana unnie and me of course. Jeongyeon unnie was annoying that bunny. Well that's nothing new. They are always like this. I then focused on my food. After having my lunch i got up. My friends were still eating. Then i felt my phone buzzed. Who could it be? ' I thought. Then I looked at my phone to see who it was . Unknown: Meet me on the first buildings rooftop 15 minutes later.    Me: Who are you? Unknown: Come here and you will know. This is what it says. But I don't remember giving my phone number to someone. That's weird. This is giving me a headache already. I just looked at around to see if anyone is pulling pranks on me or what. But none of them were acting suspicious. I just shrugged it off. Suddenly I felt the urge on going to the washroom. So I went there. After doing my business I went to my table and saw everyone was done with their lunch. Section B already have left. That's also weird. Cause sana unnie usually doesn't go without biding me goodbye. I again shrugged it off. I saw my watch. 15 minutes have passed. I need to go there to know who it is. "You guys go to the class I am coming later." I said. "But where are you going?" Chaeyoung asked. "Somewhere. Don't worry I will be back." I said while going to the way of rooftop. I then started to run. Then I reached the rooftop. Just to find there ............. No one. Huh?! Is that some kind of joke? I looked around and saw no one. What kind of prank is this. Seriously. When I was about to leave a voice stopped me. "Wait!" Said the voice. I looked back and saw sana unnie. Was she the one who messaged me? "I was the one who messaged you." Sana unnie said. "But how did you got my number?" I asked curiously. "I asked it from your friend chaeyoung." Sana unnie said smiling. She then started to move close to me. My heart started to beat fast again. God why does she has to be so perfect. We were decent far from each other. Everything got silenced. She was staring at me . I also stared at her eyes. Those eyes attracted me the most. The person who will be with sana unnie in the future will be damn lucky. Sana unnie could be a loving wife. I wish I could marr- wait what am I thinking. I am sure she doesn't seee in that way. Seeing that everything is awkward between us right now I thought of break the silence. "Uhm. Sana unnie do you need any help?" I said. Sana unnie nodded still staring at me. Damn those stares are giving me wrong ideas that I shouldn't have. "Tzuyu.....I need help with my heart." Sana unnie said with a longing eyes. Heart? Is she sick? How am I going to help her if that's the case? All these questions were going in my mind. "But how am I going to help you with your heart?" I asked confusing. She then took my hand. Her hand is so warm . If I could I want to hold it forever. She then placed my hand on her heart. "Tzuyu this heart beats so fast when I see you. This heart needs you tzuyu." Sana unnie said still with the loving eyes and softly. "Tell me Chou tzuyu what do I have to do to make you mine and only mine?" What? I am not dreaming right? This has to be a
