One is depressed, one is funny, one is suffering, and one is strong and brave.
Seemingly two completely different lives, two people who seemed like they would never become friends accidentally entered each other's lives and became out of control from then on.
Haili accidentally came into Doan's life, and the two became close friends. It was Haili who always took care of Doan. It was like biological sisters who were separated since childhood and met by chance when they grew up. They knew and cared about each other even more than themselves. Why did Haili appear?
Doan's life is so miserable and difficult. Fortunately, she has Hailey. She always seems to appear at the right time when Doan needs it most. Until one day, they both fall in love with a boy at the same time. Doan starts to hate Haili a little. She also hates her dependence on her. In an accident, Doan accidentally hurt Haili, and Haili was bleeding. Doan was frightened and fainted.
When Doan woke up again, something seemed to have changed. She couldn't tell whether her best friend was in a dream or reality. She was confused. She only knew that she had been diagnosed with depression, but something seemed wrong until she began to wonder whether Hailey was real, who Hailey was, and why she appeared.
