In a not-so-distant future, humanity has developed advanced robots known as "mechas," capable of simulating human emotions and behaviors. In this dystopian world, a boy named David is created by a company to be the first "child" of the species. However, David is not an ordinary child; he is an artificial intelligence model that yearns for love and acceptance. His primary desire is to make his adoptive mother, Monica, truly love him.
When Monica's life takes an unexpected turn, David is abandoned, and his world collapses. Trapped in a hostile environment, he embarks on a desperate quest to become a real boy and win his mother's love. Alongside a robotic dog named Teddy, David dives into a journey through a world filled with dangers and wonders, where he confronts other mechas and humans who do not understand his longing.
As his odyssey progresses, David discovers the complexities of humanity and the loneliness that can accompany the search for acceptance. Amid moments of awe and melancholy, the story explores profound themes such as the nature of love, sacrifice, and the quest for identity in a world where the line between the human and the artificial blurs. Ultimately, David seeks the hope that true love can prevail while exploring the depths of what it means to be truly human.
