I love you in my heart.

Changshan broke up with his son Zhijia because he disobeyed his father's orders about marriage. Heartbroken, he took refuge on a small island and worked as a lighthouse keeper for seven years, so he developed a withdrawn and stubborn character. Zhijia married Yue Ming and gave birth to her daughter Yu Lian. But when Yu Lian was three years old, Yue Ming couldn't resist the temptation of money and left her father and daughter to go to Hongkong with others.

Because of his serious illness, Zhijia spent all his savings and lost his ability to work. His life became very embarrassing. At the age of seven, Yu Lian had to bear a heavy burden of life and make a living by selling chewing gum. One day, I happened to meet the bright moon coming back from Hong Kong. Yue Ming found Zhijia and expressed her regret, but she couldn't get Zhijia's understanding. Soon, Zhijia died, leaving Yu Lian alone. According to Zhijia's wishes, the landlord sent Yu Lian to the island to be raised by Grandpa Changshan.

As soon as Changshan saw Yu Lian, he took it out on Yu Lian, not only letting her spend the night in the sheep shed, but also scolding her from time to time. But Yu Lian, a clever and sensible child, silently helped Changshan do this and that, and touched his lonely and cold heart with his true feelings. When he learned that Yu Lian was forced by life and took on the hardships of life with his weak body, he was greatly shocked and finally changed his mind. The two granddaughters lived together from then on.

At this time, Yue Ming also came to the island, trying to find Yu Lian to make up for her failure as a good mother. But Changshan scolded her angrily. Soon, Changshan was diagnosed as terminally ill, and time was running out. In desperation, for the sake of Yu Lian's future, Yu Lian had to entrust Yue Ming to raise him, so that Yu Lian could receive a good education. Mingyue came to meet Yu Lian, and Yu Lian didn't want to leave her grandfather. Changshan had to endure the pain of separation of flesh and blood, and "denounced" Yu Lian, forcing her to leave herself.
