~PROLOGUE~

On May 16, 2000...

"How long do we have to wait?" Sehun asks. "Just a little longer little ones," the nurse replies, "then you all will get to see your sister." Once the twelve boys heard a small cry through the door, they all shouted in happiness. Their father opens the door, "Go inside," he replies, "your sister is here, go to umma." The twelve boys enter the room, their little sister was quietly sleeping in her mother's arms. "Let Minseok hold her first," their father replies, "he is the oldest and he's more responsible." "Appa, what's her name?" Tao asks. "Her name is Yumi," Luhan replies, "Minseok told me while we were waiting in the hall." Their father gives Xiumin the baby girl, Xiumin rocks the baby like what he did to his brothers when they were born. 

Three days later...

"Halmeoni, we're back!" Tao shouts from the front yard. "Shut it, Tao!" Sehun replies, hitting the back of Tao's head. Luhan carried the car seat that Yumi was sleeping in, his father promised him that he'll let him hold the car seat. "Go play around," their mother replies, "just play in the front yard with halmeoni." The brother's couldn't wait until their sister grew up, they wanted to be with her all the time.

While Yumi was sleeping in her baby swing, the twelve boys stared at her for ten minutes while their grandmother's were preparing breakfest for them. "She's so cute," Kai replies quietly, "I want to play with her when she's gets older." "Be quiet a little," their grandmother replies, "Yumi is sleeping right now." The boys nod at their grandmother, and decided to come up with a nickname for her. "How about Yumia?" Chen sugguests. "Yuna could work too." Tao replied. "Okay," Kris replies, "Those nicknames can work, we can call her Yumia when she's a baby, but we call her Yuna when she's in school." "Good idea, hyung." Lay replies, giving Kris a soft pat on the back.

When Yumi was about four months old, the brothers started hanging out with her and called her Yumia for most of the time. "The kids are growing fast," their mother replies, "they love to play with Yumi a lot." "I know, Hye Jung, they love our daughter no matter what." their father replied. "Heechul, the boys are getting older," Hye Jung replies, "in the future, we're going to pass and no one is going to take care of Yumi." 

About two to three years later, while the boys were outside with their sister, there some bad news about a plane crash. "Excuse me," a messenger replies, "there were some passengers that lived in this household and they passed." "You mean...my parents Heechul and Hye Jung died in the plane crash?" Kris asks. "Yes," the messenger replies, "I am sorry about your loss, but they wanted to give you this letter before they passed." 

To our dearest sons,

우리의 소중한 아들,

"Omma....appa, why do you have to leave us here?!" Luhan exclaims. All of the boys and Yumi started crying after reading the letter, the grandmothers embraced them with love. "Don't cry children," one of the grandmothers replies, "halmeoni loves you all and we'll protect you all." 

After the funeral was over, the burial of their parents were on Yumi's third birthday. But, the brothers and their sisters managed to live with their younger sister with their grandmothers, all they needed was each other.
