No matter how hard he worked, his grades couldn't surpass Su Yan's, no matter how genuinely he built relationships, he didn't have as many friends as Su Yan. And as for looks, he was handsome, but Su Yan was a bona fide heartthrob. In every respect, he felt he couldn't hold a candle to Su Yan, and he lived a very suppressive life. Within this chronic suppression, he'd often think how wonderful it would be if Su Yan were to disappear. Without Su Yan, he, Cheng Tianhao, would be the best!
Awhile ago, when Su Yan got kicked out of the Su Family, and he became the heir, that was the most liberating two months of his life. It also made him realize that all these years, he wasn't always second to Su Yan because he was any less, he was born under an unlucky star. If he were the legitimate heir of the Su Family, what would Su Yan be then?
Absolutely nothing!
