Han became a successful person. He looks at the photo on his table and recalls old memories of the time he spent with his old friend, Bao. Memories of the past slowly emerge, they used to live happily together until one day a bad boy, Teen, came and bullied him, and the brave Bao barked at the bad guy to protect him. He also remembers they spent a peaceful night together before Bao was killed by Teen. He can still vividly recall the scene of Bao’s bloody corpse lying next to the trash. Memories slowly fade, Han is crying, then he walks away from his office, leaving the picture on the table.
