Caio

When he was just two years old, Caio was mysteriously left on the doorstep of Dona Lúcia, a simple woman who was already the mother of a daughter named Ana. Since Ana lived with her father in another city for her studies, Caio grew up as an only child, without knowing much about the so-called "sister" he had never met—not even a photo of her, as Ana's father was controlling and didn't allow contact with her mother.

Now 18, Caio is a reserved and dreamy young man. His life changes completely when Ana, now 19, decides to return to live with her mother to finish college in her hometown. From the very first meeting, Caio feels something inexplicable for her—love at first sight.

But when he was 12 years old, his mother is a donor and told the truth that he was left on the doorstep, but she loves him as if she were his real mother. The day was coming when Ana would arrive and see her mother after so long.
