[Why did Yan Yueqing try to prevent Du Mansheng from donating blood? Is she trying to show off how kindhearted she is or something?!]
[Not necessarily. President Yue has many ways to show kindness; there's no need to be stubborn about it at this moment! I think there must be a reason.]
[Hold on! Am I the only one who noticed—why do Song Xiaoyu and Song Hui, the couple, have different blood types?!]
[Different blood types are normal, aren't they? My mom is A, my dad is B, and I'm type O.]
[Parents being AB and the child being O is normal. But if both parents are type O and the child is type B, that's not normal! It's not impossible, but the probability is extremely, extremely low! Basically, only a mutation could explain it.]
[What do you mean? I don't understand.]
