Olivia had no idea about Ethan's blood type. Kelvin explained, "Mr. Miller's blood type is the rare P1 type."

When Olivia heard that, her vision turned black. She almost fainted on the spot.

She had learned medicine before. So, of course, she knew how rare this blood type was.

The P blood group system was a different system from the ABO and RhD systems.

It was categorized into five types: P1, P2, P1k, P2k, and P.

P1 and P2 were more commonly found, and the last three types were even rarer.
