Song Jihyo and  was discovered by a S.H.I.E.L.D. team in Ilsan, Korea, and was herself an 0-8-4. The entire people in Ilsan and nearly the whole S.H.I.E.L.D. team got killed protecting her. She grew up at the orphange and in different foster homes who never kept her around for long, saying that she "wasn't a good fit". When she was nine she stayed with a family, called the Brodys, from America that Skye particularly wanted to like her, but they soon sent her back to the orphanage. It is revealed in "Seeds" that the S.H.I.E.L.D. protocol covering her placement at the orphanage mandated her constant reassignment.

Song Jihyo became obsessed with finding out the truth about her parents used to do, and eventually she ran away. At some point later in her life she joined the Rising Tide, a computer activist (Or as Song Jihyo would say, "hacktivist") group. Song Jihyo and the Rising Tide shared certain beliefs about the freedom and accessibility of information. It was through the Rising Tide, that Song Jihyo bonded and became involved with master hacker Cho kyuhyun.

Song Jihyo spent two years living out of her van and using her skills to reveal classified data to the public while searching for information about her parents. However, in all of her searching, the only evidence she was able to find about them was a document with all of the pertinent data redacted by S.H.I.E.L.D. It was then that she came on to the idea to infiltrate S.H.I.E.L.D. Soon later she bacame an agent after spending a few years old with S.H.I.E.L.D. she was told to find person with a very high criminality and killed them. S.H.I.E.L.D is a very private company that no one even know they were existed. But after she works thre she still could not find anything regarding to her parents and the company. She decided to leaving the company without anyone knowing, she flew to Korea and bought a mansion with her own money that she saved. As she was on the plane she started to think about her long lost brother Seungri, she wondered how he's doing or does he still remember her.

Seungri he is now living alone in his apartment that his foster family bought for him. He thanked them for taking a good care of him since he was little, it is now time for Seungri to live by himself. He started to think how his going to look for his sister, all he got is a number of the orphanage house. Hes been ask them about his sister but they said that she was disappear when she was out in the park playing. Seungri now is in lost, he took out a picture of him and Song Jihyo when they were little, in the picture Song Jihyo and seungri were laughing at eachother "I miss you noona, please help me to find you" he thought and he can feel a tear escaped his eyes.
