결혼하지 말 걸 그랬어

Five years ago, we fell in love, but his mother forced me to leave him. Shortly after we broke up, I discovered I was pregnant! Initially, I had decided to raise the child on my own, but the child was diagnosed with leukemia and urgently needed a bone marrow donation. Helpless, I sought him out, hoping he could save our child. However, his fiancée continuously interfered, creating numerous obstacles. Will my child survive, and can we get back together?
