Cha Jung sook, a mother, housewife, good DIL. Who had a lungs transplant realised how her family was so selfish. Her husband doesn't even bother doing a organ donation for her. Her MIL treats her like a maid. Finally the near death situation opens her eyes and she decides complete her residency that she had dropped years ago, during her first childbirth. She clears her residency exam and joins her husband's hospital to practice. There she find out her hunsbands infidelity, gains everyones love, respect, support and saves many lives.
But at the end she turns out to be just a stupid prrson, who neglects her health and her liver fails again. Imagine being urself into medical profession. You just survived death because, some somewhere died and donated organ to you and you have no respect for them, as you are busy dwelling in your sorry state. Such disrespect and waste of people's effort.
I've no sympathy for this lady. One who doesn't respect themselves, no one else respects them too.
