Because she understands Nangong Jin, once he takes something seriously, he absolutely won't give up on it.
Nobody can change his mind.
Just like how Nangong Jin was determined to dance in the past, and he reached the top of the world with it, and then once he decided to quit, he resolutely didn't touch it for ten years.
No matter how many people invited him, he remained unmoved.
It's the same with the family business, once he seriously said he would take over, he meant it.
What she was worried about earlier was that Nangong Jin seemed a bit of a libertine who loved freedom, and might be just toying with Di Jinxuan.
But now it doesn't look like toying at all; he's very serious, so under such seriousness, she doesn't mind if her son gets busy with the bedroom activities a bit earlier.
As long as Di Jinxuan is willing, she really has no objections, so she's of course delighted to see the two of them in love, and she feels it very, very much.
