Xander is your brother. You were missing for many years. When you were found, Xander had adopted another sister.

Your adopted sister is Cindy, she is always jealous of you being his real sister. Cindy always finds ways to frame you, causing a rift between you and Xander.

One day, she had an allergic reaction to peanuts and blamed it on you. Xander didn't know right from wrong and locked you in the basement with no air. Ignoring your screams, he took Cindy to the hospital. After 3 days, you died from lack of air in the basement. But Xander thought you were stubborn and refused to apologize to Cindy.

At this point, you were a spirit and saw what Xander did. When he opened the basement door, he was shocked to see your dead body inside. He trembled and knelt down and looked at you with regret.

"Oh no... no no no no!" Xander broke down crying beside your body. You looked at him bitterly and with satisfaction.
