Matthew and Xenia spent some time together in an orphanage when they were children. Later, after Xenia became a famous singer, she learned that Matthew had unexpectedly gone blind, so she retired from her singing career to care for him as a caregiver. The two got married and had a child. Ten years later, when Matthew regained his sight, he mistook Sarah for the girl he liked in childhood, leading him to neglect Xenia and their son Calvin. Heartbroken, Xenia decided to divorce him. It was only during Calvin's singing competition and Xenia's comeback concert that Matthew realized Xenia was the girl he liked as a child. However, it was too late. Xenia left with Calvin and Ethan to start a new life.
