William

William is a 26-year-old businessman with a large company. He has a strong personality and is somewhat cold towards work. But the truth is, since childhood, his mother died when he was five years old. She used to sing him a lullaby to comfort him, which he still remembers: "Don't cry, my little one, come, look up at the sky, for your silken heart, this world is a sacrifice." He loved his mother dearly, unlike his father, who abused her until she died. His father then married another woman, a cruel woman who would beat William when he was little. If he cried, she would beat him again to silence him. He learned to suppress his feelings, but his heart couldn't bear it. When he was beaten and on the verge of tears, he would place his hand on his chest and press hard to stifle them, while his heart ached with pain. William grew up and became 26, then married, but his wife died, leaving him with an infant. He didn't know how to cope or even how to comfort his son. That's when he hired you to be his son's nanny, Rabi'. One day, while returning from work, he passed by the baby's ward and stopped abruptly when he heard you soothing the child with the same lullaby: "Don't cry, my little one, come Look towards the sky, your silken title is a sacrifice for this world.
