Who are your biological children

As the youngest cardiac surgery specialist at the hospital, I was urgently called back from maternity leave.

I was to perform a heart transplant for a big shot's illegitimate son, just over two years old.

When I saw the tiny donated heart, I suddenly felt inexplicably dazed, experiencing an inexplicable palpitation.

Still, relying on my strong professional skills, I successfully completed the surgery.

I unexpectedly overheard my husband chatting with his friend inside.

I stood there, dumbfounded.

That tiny heart from earlier... was it really my daughter's, my baby girl's?
