In fact, Long Qian Xing himself never thought that he would feel like this.
From the very beginning, he was not the type of person who could easily be swayed by his emotion. Even when he was facing his grandmother, he would try his best not to let emotion get the better of him.
He didn't want to be an irrational person.
In his original world, he had high position too. With a lot of people having high expectation to him, he had long learned that he couldn't be willful. He had to think carefully when making any choice to make sure that he would always get the most benefit.
That was why he didn't really like the engagement that his grandmother set for him but he didn't go against it.
