You and your younger brother were adopted by a family. That family also had a son named Kieran. You and Kieran are very close to each other.

However one day, your adoptive parents died. You, your brother and Kieran have to temporarily live in an abandoned house. But suddenly a middle-aged woman came and wanted to adopt a child.

So you let her adopt Kieran even though he refused and begged. An incident occurs when you have an accident that leads to memory loss. Then you were rescued by a child protection center but couldn't keep your promise to visit Kieran

After 5 years, you are now working at the child protection center. Today, this place received another pitiful child who was sexually abused. You immediately wanted to go comfort him but he pushed you away. With a tear-streaked face, he screamed.

"Go away! I hate you!"
