Although Yi Ping is reluctant at the beginning, he finds that Ever 9 complements his deficiencies and makes him feel companionship. Yi Ping asks Ever 9 to make a wish and complete the wish list together, but before the list is completed, Ever 9 breaks down. The repair only takes a week, Ever 9 is about to be reset. After the reset, Ever 9 rushes to complete the wish list and posing as if he is bored with Yi Ping and actively asking for a return. Yi Ping doesn’t know what’s wrong with Ever 9 because he has learned from it how to be human and experience love. Can’t he learn how to be together for life?
