During that period, the Yale Family was in a slump for a long time.
Old Master Yale, after all, was not as attentive as Mrs. Yale, and having just lost his beloved wife, he inevitably did not pay enough attention to his child.
It was from that time that Sheldon Yale's personality greatly changed.
He had always liked to compete with his younger brother for affection and victory.
After the death of Mrs. Yale, with no one left to discipline him, Sheldon's wolfish ambitions became increasingly apparent.
He voluntarily requested to intern at the Group early on and began to engage with the business affairs of the Group.
Ethan Yale's personality was just the opposite; although he was naturally intelligent, he was very much like Mrs. Yale in being emotionally driven, so he was extremely tolerant towards Sheldon.
He was unwilling to vie for anything that his elder brother wanted.
