[3rd Person POV]
"Oh little brother, snooping are we?" Changkyun heard as he bolted upright with widened eyes. He stood face to face with Chaehwa who had her arms folded and suspiciously glared at her younger brother. She tried to look closer to see what he was doing but Changkyun quickly slipped the photos underneath a pile of folders on the desk.
"Snooping? I was sent here to take some photos of a document" Changkyun lied but in a relaxed tone so he wasn't caught. Chaehwa frowned as she shook her head. Changkyun couldn't lie that easily to her and get away with it. 
"Maybe that was why you came in here, but that wasn't what I caught you looking at." Chaehwa said as Changkyun sighed deeply. There was no way he could lie again to get out of this situation, Chaehwa had already caught him. 

Before Changkyun realised, Chaehwa had moved to stand right in front of him. His eyes widened as he took a secret glance down at the photos he had pushed underneath a pile of folders but the corners of them were still visible. 
Chaehwa and Changkyun stared at each other as Chaehwa moved the pile of folders to one side to reveal the photos beneath them. She glanced down as she gasped and a horrified look spread across her face, "Oh no."
"Oh no? You know what they mean, don't you? Why does our mother have a photo of Kyungah and a baby on her desk? Is Kyungah the baby?" Changkyun asked Chaehwa in disbelief as she continued emotionless, silent and staring at the photos, "Chaehwa!"
Chaehwa snapped out of her daze and looked across at Changkyun who looked completely confused, she sighed deeply as Changkyun frowned. Just as he began to ask her again, she interrupted and hesistated so he stayed silent and waited for her answer.

"The baby is Kyungah and the hand in the photo is our mother's..." Chaehwa began as Changkyun frowned again and looked back down at the photos. Immediately multiple thoughts rushed through his mind and he didn't know what to believe, but he knew that Chaehwa must know what it all meant. 
"Why... why would our mother be with Kyungah as a newborn..." Changkyun stuttered as Chaehwa shut her eyes tightly and sighed deeply. "Is Kyungah... our sister?!" He asked her afterwards as Chaehwa's eyes opened quickly and she shook her head.
"No no no. You're not related to Kyungah, she isn't your sister. I only found out a few years ago, Chaewon and I..." Chaehwa began as Changkyun sighed with relief but his eyes widened afterwards. At least he wasn't related to Kyungah, but Chaehwa wasn't the only one who knew, so did Chaewon, which meant the whole family knew apart from him, "Chaewon and I found our mother looking at the same photos. When we asked her about them, she told us everything but she told us to never tell you..."

"But I want to know. I have a right to know, and so does Kyungah!" Changkyun said sternly as Chaehwa gulped at the angry tone in his voice.
"I never knew it was Kyungah when our mother told us, she never said her name. I only worked it out when Hyunwoo said something to me yesterday. I never thought it could be Kyungah, I still don't understand why our parents would let her live here because of what happened." Chaehwa pleaded with Changkyun as he remained emotionless. 
"So what is it? Tell me everything you know." He sighed deeply as Chaehwa reluctantly nodded and she carefully took Changkyun's hands in hers. Changkyun shook his hands out of the way and put them to one side, futher away from Chaehwa as she sighed deeply and brought her hands back, then she began to tell Changkyun. Everything.

"I'm so thankful she's ok" A woman's voice said as she pressed her hand against the window of the viewing room where her baby girl laid in a hospital cot. A man stood behind the woman emotionless and silent as he also looked into the viewing room at his daughter before he glanced at a baby boy who was laid in the cot beside. Both of the babies who had been born at a similar time had been sent to the room where all newborn babies were held if their mothers have complications after their birth, but luckily the girl's mother had recovered quicker than expected, compared to the boy's mother, however both of the babies were healthy.
"Mrs Im?! We just need to check your blood pressure again." A doctor said as he approached the couple stood at the window and Mrs Im turned around with a smile on her face.
"Is everything fine with our baby?" She asked the doctor as he immediately nodded.
"What about the boy?" Mr Im asked the doctor as he let out a slight sigh and Mrs Im frowned at his question.
"I shouldn't
