Serena’s POV
“May I know your blood type, Mr and Mrs. Walter?”
“I’m O positive,” Catherine answered.
“I’m B positive,” Tyler answered.
The nurse looked at them alternately with confusion, “Uh…your son’s blood type is AB negative. I don’t think either of you can donate.”
AB negative? I was confused but I immediately dropped it as I lifted my arm, getting the nurse's attention.
“I’m AB negative.”
They all looked at me. Harry immediately held my hand tight and looked at me worriedly, “Serena, you’re injured.”
I looked at Tyler, ignoring Harry. “I’m fine. I can donate blood for him. Andy’s safety is more important.”
He sucked his breath as if he’s having a hard time, “Serena…”
I then turned to Catherine but she’s just looking at me. I sighed and looked at the nurse. “I’m gonna donate. Where should I go?”
“Serena, I said no!” Harry’s strict voice caught my attention.
