Lu Han came to find out the surgery time on behalf of the Lu Family.
He could have simply called Xu Bo to ask, but Lu Han wanted to see Tang Su and was happy to make the trip himself.
As experienced elders, Lu Maoyan and Bai Wei understood the longing of young lovers in the throes of passion and allowed Lu Han to come. They did not accompany him.
His father had already personally cleared up Granny Su's misunderstanding, and they had found specialists for her. Bai Wei's view was that they only needed to treat Tang Su's parents well.
As for Tang Su's grandmother, they had done what they could, and it was now up to her to come around.
If she couldn't, then at the end of the day, the Lu Family didn't strictly need the old lady's approval to take a bride.
It was enough to maintain face; they didn't have to lower themselves too much for someone who wasn't that important.
The only people who could make them truly lower their guard were Tang Su's parents, her direct relatives.
