The DramaNext guide
What Blood Is Not Bond is about
A routine medical checkup tears away the ugly truth behind a family’s love. Doctor Jessica learns that her older sister, Sarah, has leukemia—and Jessica is the only compatible bone-marrow donor. But donating would mean giving up the baby she fought so hard to conceive. Jessica tests her family by pretending that she is the one who is sick and that only Sarah can save her.
iDrama released it as 23 bite-size episodes mixing marriage drama, secret identity and family secrets, made to watch on a phone in one sitting or a few.
Is it worth watching?
The draw here is a marriage that starts on the wrong foot and has to be earned. On top of that: waiting for the truth about who the lead really is to come out.
The whole series takes about 28–51 minutes, so it's an easy binge.
