How these ratings work
There is no single official chart. Japanese magazines and Korean TV shows each publish their own, but most agree on a few patterns: A and O are the classic "best match", A and B are the famous "hard work" pairing, and B and AB get along easily because AB shares the B allele. Our hearts follow that common ground.
Compatibility charts are entertainment. Real relationships depend on communication, values and timing, not on antigens on red blood cells. If you want the science side of blood types, try the baby blood type calculator or read what research says.
