The Love of Green Rock Grass

[Workplace elites return to school + bitter first, then sweet + both of them are slow to warm up] Ling Xiao and Du Changxing jointly studied in the BM on-the-job graduate class of Chunda Business School. Du Changxing has a daughter, Du Muchen, who was born out of wedlock. Both of them suffer from type R chronic heart failure, a rare genetic disease for which there is currently no specific drug treatment. He originally wanted to keep the secret of participating in the clinical trial because there was a bigger secret in it, but he didn't expect that the project manager of this clinical trial was his classmate Ling Xiao! Ling Xiao and Du Changxing know Qingyancao very well, what is the origin of this... Ling Xiao: A top student, if your father doesn't love you, your mother won't love you. The love theorist is just a little white rabbit. Du Changxing: He seems cold, but he is actually affectionate and extremely tolerant.
