An unknown incoming call appeared on Kitty's phone, it was Suki, her secondary school mate whom had not been in touch for years. Surprised, Kitty excitedly asked about Suki's life. To Kitty's bigger surprise, Suki told that she would like to hear her voice one more time, as she was crying and talking at the edge of the roof, a moment from jumping to death. Stunned, Kitty kept asking and asking, "Where are you?" The only answer she got was her unstoppable weeps, followed by a good-bye. Thrilled with a flood of fears and having no ideas what to do next, Kitty wandered to and fro on the street... Kitty decided to rush to Suki's roof in the hope of saving her life. To her surprise, it was a journey of knowing life.
