As Marina and Jack continued their journey, they came across a small island with a beautiful lighthouse. Marina was immediately drawn to the lighthouse and begged Jack to let her explore it. Jack, always eager to make Marina happy, agreed and they docked their ship on the island.

As they walked towards the lighthouse, they noticed a group of children playing on the beach. Marina's heart swelled with joy as she watched them laughing and having fun. She couldn't help but think about how much she would have loved to play with other children when she was younger.

Feeling a bit homesick, Marina decided to sing a song for the children. As she sang, the children stopped playing and gathered around her, mesmerized by her voice. They had never heard anything like it before.

One of the children, a little girl named Lily, approached Marina and asked if she could teach her how to sing like her. Marina was touched by the girl's request and happily agreed. She spent the whole day teaching Lily and the other children how to sing and they all had a wonderful time together.

As the sun began to set, Marina and Jack said goodbye to the children and continued on their journey. But Marina couldn't stop thinking about the children and how much she enjoyed teaching them. She realized that she didn't just want to be a singer, she also wanted to be a teacher.

With Jack's support, Marina decided to start her own singing school for children. They traveled from island to island, spreading the joy of music and teaching children how to sing. Marina's school became famous and many parents would bring their children from faraway lands just to learn from her.

Marina was living her dream, and she couldn't have done it without Jack by her side. They continued to travel and perform together, but now they also had a new mission - to spread the love of music and inspire others to follow their dreams, just like Marina did. And they lived happily ever after.
