After the fake young master left home, he discovered that it wasn't raining at all outside.

Protagonist-centric! The male lead is the darling of the group, a succubus who spoils everyone he goes with! No romantic pairing (not a traditional face-slapping, feel-good story; more slice-of-life).
Is Wen Rang a fake young master from the richest family in the capital? Facing the crisis of being kicked out of the Wen family and losing everything, Wen Rang doesn't care at all. Let him go, so what?
He wanted to help his "struggling family" get rich, but he discovered... something wasn't quite right.
What?
Is the eldest brother the all-powerful president of Country H?
Is the second brother a business tycoon who controls the global economic lifeline?
Is the Indian leader the leader of "Dark Night," the world's largest military force?
And how did he, after changing his name to Zhu Yan, become the young master of the oldest reclusive family in H country? He thought that the road to wealth after leaving the Wen family would be arduous and bumpy, but he never expected that his life would be pampered by the whole family, with bigwigs from various countries kneeling on one knee, opening their hearts, and listening to his every word.
