Why Does Mio Leave His Foster Parents In 'Mio, My Son'?

Rhea Ravelle, heiress of a powerful and influential family, goes against her family's wishes and cuts ties with them. She chooses to marry Carter Jamison, a man with a failing career and two children born out of wedlock. For six years, she raises his children as if they were her own and helps Carter rebuild his crumbling business. Under her care, the kids grow into kind, well-mannered little stars, and Carter's company finally makes it big and goes public. But right at the celebration marking his entry into high society, the biological mother of his two children suddenly shows up. And Carter, who is usually so calm, completely loses it. He begs the woman to stay, making Rhea the laughingstock of the entire city. That night, he doesn't come home. Instead, he takes the children and runs straight back to his old flame, playing house as a happy family. Soon after, Carter files for divorce. "Thanks for everything, Rhea. But the kids need their birth mother." The children's mother also says, "Thank you for taking care of them all these years. But a stepmother will never compare to a birth mother." So blood beats love? If that's how it is, then she's done playing stepmother. However, the children reject their birth mother flat-out, and they don't want Carter either. They declare, "Rhea is our only mom! If you're getting divorced, then we're going wherever she goes!"

I'm adopted by my parents. They are very nice to me—so nice that they keep praying for my health and happiness before my bedtime every night. Later on, Mom is pregnant with a baby. I hide under my blanket and spend the night crying. Then, I secretly pack the tiny suitcase I've brought with me. But my parents don't send me away. Instead, they treat me even nicer. On the day my little sister, Freya Walker, gets born, Mom takes my hand and pats me gently on the head. "You're an older brother now. That's why you have a little sister to be with you." Dad lifts me over his head while spinning me in circles happily. "You really are our lucky charm, Ash! You'll always be our beloved darling!" Finally, I don't have to keep worrying about getting kicked out. From that day onward, I really think that I've become a part of the family. That is, until Freya smashes my favorite toy car model one day. I'm so angry that I smack her on the spot. She stumbles away from me, soon plopping to the floor. At first, she's stunned for a few moments, only to start bawling immediately after. Mom loses her mind instantly. She shoves me away before scooping Freya into her arms and keep asking her if she's hurt. Dad rushes over and starts strangling me immediately with frighteningly bloodshot eyes. "We've kept you around for so many years, and yet you have the gall to bully Freya? Believe me when I say I'm definitely sending you back to—"

After being missing for eighteen years, I was finally found by my wealthy birth parents. The impostor—the young man who had taken my place all this time—dropped to his knees, sobbing. "Goodbye, Mom and Dad. Thank you for raising me. Now that Jason is back, this family doesn't need me anymore." My parents hugged him with heartbreaking tenderness. "Don't be ridiculous," they said. "You're our only real son." Even my fiancée confessed her love to him. "I don't care who you really are. You're the only one I love." They all orbited around him, like planets around the sun. When I was nearly killed in a car accident, they were too busy throwing a birthday party for his dog. So I packed my things in silence. Without a word, I accepted an invitation from the space agency to join a five-year satellite research mission in complete isolation. Yet after I left, it was like the whole family lost their minds. They scoured the entire country, desperate to find any trace of me.

I struggle with all my might, but Dad restrains me, and Mom breaks my limbs. Then, my sister seals me into the concrete. "Concrete is only brought to life with an actual person sealed inside. It looks so much more defined! It's not like you'll die after being sealed in there for a few days. How can you be so insensible?" The pain of having my limbs broken and my oxygen being cut off leads to me dying within that block of concrete. My body rots and festers inside, but my soul sticks around to watch how my parents dote on their adoptive child. They seem to be happy without me. Finally, I lose all hope in them. But when the liquid from my body seeps out of the concrete, they all lose their minds.

In my previous life, my sister thought that since my husband and I had high-paying jobs, she could swap her son with my child without anyone noticing. But twenty-five years later, the tables turned. My son had grown into a street thug, while her son—raised under my care—rose smoothly through life. Young as he was, he had already become a CEO. He was dutiful, bought me a villa, and even sent me traveling around the world. My sister barged into his company, waving a DNA test report, kicking up a scene, only to be thrown out by security. "Mr. Kieran said that even if you are his biological mother, you never gave him a single day of care," they told her. "So he refuses to acknowledge you." Breaking down completely, she drove her car into me and ended my life. When I opened my eyes again, we had returned to the very day she switched our babies. This time, my sister clutched her own child tightly, a wild, triumphant grin on her face. "From now on, you can be the mother of a street thug," she sneered. "The villa and all those riches—they're mine!"

I spent ten years raising my stepson. Even though he never once called me 'Dad,' I never let him go without. Food, clothes, tuition, living expenses, I paid for everything. But on New Year's Eve, during the family reunion dinner, he suddenly spoke up in front of everyone. "Old man, I've got my eye on that apartment in the old district that's about to be demolished. Transfer it to me. I'll use it as my wedding house." I frowned. "That apartment is meant for your mother's retirement and your sister's education. Pick another development instead. I'll help cover the down payment." He slammed the table. "A down payment? That's nothing. "You want me to carry a mortgage at my age?" Then he looked me dead in the eye. "If you refuse to transfer the property, believe me, I'll make my mom divorce you." Instinctively, I turned to look at my wife beside me. But she only lowered her head in silence.
