Rio has always lived a life of luxury from his family; he is the only child. His entire family loves him dearly. Everything Rio ever wished for came true, making him incredibly fortunate. One day, something unexpected happened: Rio's parents were in an accident and needed a blood donor.

Rio wanted to donate blood to his parents, but the blood didn't match at all. Rio couldn't believe it, so he decided to have a DNA test done on his parents. Rio was shocked to learn the truth: he wasn't their biological child.

After learning all this, Rio could only grieve. After his parents realized, Rio told them he already knew everything. Rio's parents said that Rio would always be their child, as he was a gift from God given to them.
