俺は本当に世界一大富豪の後継ぎじゃないんだ!

Andrew made a living by repairing cars, day after day. After a reunion with his fathers' old classmates, Andrew and his father were mocked, leaving him feeling depressed. However, his father encouraged him, saying that as long as he worked hard, he could achieve success. To live a better life, Andrew unexpectedly accepted a job to take care of someone else's child, which provided him with a generous income. Years later, Andrew, through his own efforts, opened a car repair shop and achieved great success in his career. After going through various twists and turns, Andrew ultimately realized his dream - not only allowing his father to live a good life, but also finding his long-lost mother. His relationship with the adopted child also became increasingly close.
