After I Left, He Regretted It Too Late [Reborn]

[Powerful, gentle, and restrained top x resilient, self-reliant, beautiful academic bottom] Looking back on his previous life, Shu Ran had always compromised for things he could never have. He longed to be loved and accepted by a family, but all he got in return was one deception and scheme after another. After dying, he was reborn at nineteen, in the first year after leaving the Shu family. Shu Ran decided to live for himself. He left the scumbag and cut ties with his family of origin once and for all. He no longer longed for anyone to love him. Instead, he would work hard to pursue the future he wanted. He would no longer stay for anyone. Yet the people he had once longed for and depended on all turned back for him, begging him not to leave. His usually cold parents, eyes red, begged him to come home. His always refined and proud older brother went mad and made a pitiful spectacle of himself, begging for forgiveness. As for the man who had once treated him as a plaything and stand-in, he now kept saying that Shu Ran was the one he loved most, and that his feelings were real. [But it was all too late.] [You lower your heads, you regret it. Who are you putting on this act for now?] / Half a year after Shu Ran vanished without a trace, he reappeared as a specially invited expert at an international science and technology forum. The scions of wealthy families who had once looked down on him stared at him, radiant onstage, and lost themselves in the sight. One after another, they wondered what on earth Lu Yanzhi and the Shu family had been thinking when they threw away such a treasure. P.S. There will be revenge, but Ran's career will always come first. The love interest appears a little later, and he's not one of the people who looked down on Ran before! Theme: Be honest and live with purpose.
