"Woah... Soo Yun! You're so chubby in the past!" Yo Seob giggled and flipped to the next page of an old photo book. They had a little free time till the flight at 11pm so the Lai sisters decided to sort out some old stuff.

"Soo Yun was 5.4kg at birth." Vinny threw Soo Yun's birth certificate at Yo Seob who caught it like a monkey.

"Haha~ So cute~!"

"S-sis! Seriously..." Soo Yun puffed her cheeks in feign anger earning the laughter of her 3 elders. She looked around, wondering what she could sort out next when a silver frame caught her eye. Slowly, she picked it up. "This is..." The other 3 looked at each other before walking towards Soo Yun.

"What is it?" Hyun Seung tip toe to look over her head. In the silver frame was an old picture of a family of 3. "Tha-"

"My mother." Vinny looked away as the words left Soo Yun's mouth.

"O-oh..." Hyun Seung immediately regretted asking that question.

"My mum was a beautiful woman..." Vinny turned around to leave the room, unwilling to listen in on a painful part of her past. "But she was selfish." that stopped Vinny in her tracks as she turned to look at Soo Yun.

"She left us cause she couldn't handle the 'pain' brought about just by looking at Vinny. How stupid. Running away? Tch. How immature. Dad was no better, going to look for mum? Lies, it wouldn't take this long. He stopped contacting us since we joined Cube. Pathetic liar probably has a new family elsewhere by now. Not that I care after all..." Soo Yun turned around to face Vinny. "I've got the best sister in the world!"

Her bright smile set something off in Vinny. "Soo Yun..." She bit on her lower lip and ran to hug Soo Yun, her desperate attempt to stop her tears failed.

"There there. Don't cry." Soo Yun threaded her hand through Vinny's hair.

The two boys smiled, leaving the room silently so that the girls had some alone time. "Your girlfriend is emotional."

"Sometime sI think Soo Yun is the older sister." Hyun Seung shrugged his shoulders as they both laughed, heading down the stairs.

"But it's nice to see heart warming scenes like this. Reminds us of how we are just humans since we all come from a 'perfect' family. We can never understand their pain."

"Yeah. We can only protect them as they are now."
