AUTHOR's POV     "She's Shim Yunhee" Kai breathed out, his expression so pale that the mentioned girl thought he could have died in two seconds. Baekhyun swallowed his spit, his eyes slightly widening as he blinked them repeatedly. Needless to say that what Kai had just said had left him dumbfounded and incredulous.    "C-can you repeat it once again?I think I've misheard what you've said" Baekhyun demanded as his gaze fell on Yunhee. Was it true? Was she really his baby sister? So that was why he had found her somehow familiar...   "No hyung, you've heard right. She's Shim Yunhee." Kai stated, confusing Yunhee to no end. Why the heck were they so stunned? So what if her name was Shim Yunhee? As far as she knew, her name was quite normal and common even...   "Really? Is your name really Shim Yunhee?" Baekhyun asked her with hopeful eyes. What was wrong with that dude? Hadn't Kim Jongin already told him twice?    "Well duh. Jongin has already told you twice. And anyways, what if I'm Shim Yunhee? What's wrong with my name?" She snapped almost annoyed. First, they were keeping her away from Naeun. Second, they were behaving oddly. Third, they looked stupid repeating the same thing countless times.  She stared at the both of them, waiting for an answer. Instead she was asked something that left her shocked.    "Do you miss your brother?" Baekhyun questioned, wanting to make sure she was the one. Yunhee glared at him, how the hell did he know her brother wasn't by her side anymore? Were the two of them stalkers?!    "How do you know? Are you some kind of crazy--" She was cut off when two arms were tightly wrapped around her, almost knocking the air out of her lungs. Her ribs throbbing in pain as the night before her father had mercilessly kicked her, leaving her bruised everywhere.    "Hee-ah!" Baekhyun choked out, his eyes b with tears. He had finally found her! After years of searching he had finally found her lovely sister!  Yunhee jerked out of his grip at the way he had called her. Only her brother used that name and no one else.    "H-how do you know? Are you f-following me around? Are you stalking--" but she gasped when Baekhyun, out of happiness, shoved his wrist in front of her eyes, showing the bracelet that was shining around his wrist. In a daze, her hands slowly crept up, her fingers grazing on the silver four-leaf clover in disbelief,as if she didn't believe what she was seeing.    "Where did you buy it?" She asked still staring at the bracelet, yet not forgetting to add that cold tone which was so familiar to Kai but not to Baekhyun. When had his joyful sister become so cold?    " You know very well that I designed it and had it made just for the two of us. Hee-ah I'm your--"   "Don't call me that! Only my brother has the rights to call me that!! Why are you--"   "I'm your brother Hee-ah! I'm your Oppa! I'm Baekhyun oppa! Stop rejecting that thought because I know you're intelligent enough to get it!" Baekhyun hissed shaking her shoulders. She groaned in pain at his action, though she knew he wasn't doing it on purpose.  She looked at the boy in front of her. Was he really her brother? He wasn't making fun of her, was he? But no matter how much she wanted to believe him, it just sounded impossible. After so many years, she couldn't believe that the Baekhyun shouting at her in that moment, was the Baekhyun she had missed so much. Could she let her walls down? Could she really let herself be happy?    "I'm Hyunie, can't you believe me uh? I missed you so much Yunhee-ah...I'm sorry I left you there, I'm sorry I didn't do anything..." He apologized once again embracing her. At those words she decided to let her walls down just for a moment as she reluctantly crept up her arms to circle them around his waist but let them down again, being too early for her to open up to her brother, who was now none other than a stranger to her.  Yet she couldn't help but lean her head against his chest, after all he was a blood related stranger whom she had sweet memories with.  She shut her eyelids, letting her tears silently fall.    Kai backed away awkwardly from the scene. He would have liked to keep on staring because he hadn't ever seen that side of Yunhee and was really curious, but he had morals and he knew that he had to leave them alone.  Smiling he walked back to Baekhyun's room, ready to refer everything to the other EXO members.      ------     "What?! Really?!" The ten boys shouted in unison, eyes enlarging and mouths hanging. Had they really heard right?! The infamous little sister of their dear friend Baekhyun was talking with him in that moment?!    "Really!" Kai repeated for the fifth time. As soon as he told them about Yunhee, he was immediately thrown and incredulous look from each of his friends and asked if he had been kidding.    "I want to see her!" Chen hissed grinning widely with wicked eyes. Kris sighed at his friend 'eagerness' and smacked the back of his head, earning a whimper from him.    "Hyung~" Chen whined, pouting and rubbing his sore spot.    "Is this the only thing you can think about now? Really Kim Jongdae? Really?" The oldest of the two scolded him while the rest of the boys watched them, silently snickering at Chen's misery.    "I'm sorry okay?...and I bet you're curious to see her too, why go all crazy on me? Geez..." The poor boy mumbled with his lips pursed.    "Okay okay. He's right, we all are curious to see her..." Luhan interjected before Kris could jump on Chen and strangle him. Chen grinned triumphantly at Luhan's statement, sticking his tongue out, at which Kris could only roll his eyes. "..but we are not as eager as you are Jongdae. And stop thinking about hitting on Baekhyun's sister!" He continued and now it was Kris' turn to stick childishly his tongue out.   "Is there anyone who wants to go with me and spy on them?" Chanyeol asked out of the blue, changing topic and already heading towards the door. Despite his innocent wide eyes, DO silently rose his hand, taking small and hesitant steps towards his tall friend. Everyone's eyes followed his secretive movements and soon enough the eleven boys were all dashing out of the do
