Synopsis：Six years ago, Winni and Chester were a devoted couple—until Chester’s old acquaintance Ruth returned. Hiding behind a gentle, kind facade, Ruth befriended Winni while secretly scheming to take her place. Soon after, Winni became pregnant, but the doctor told Chester the baby shared no blood relation with him. Chester’s trust shattered, he turned cold to Winni and grew closer to Ruth. Six years later, Winni’s son Ron is dying of leukemia, and the only compatible bone marrow donor is Chester. To save her child, Winni is forced to humble herself before Ruth. Yet in the tug-of-war with Ruth, she gradually uncovers the truth behind why Chester was convinced Ron was an illegitimate child.
