And she was nine years younger than him, she was still in the prime of youth...
No!
This cannot go on.
Now that he was clear about his own feelings, and fortunately, she liked him too, it wouldn't be possible that she fell in love with someone else after just one and a half months of not seeing each other. He must go and confess his love to her as soon as possible, so that their relationship could be settled. Only then could he truly be at ease.
Having known her for so many years, naturally, he could not simply ask for her hand in marriage like the Sixth Prince of the Zhaoqi Kingdom had done. He had to confess his love first.
Every time he thought of the more than one occasion when she had said she liked him, he yearned even more to see her and to confess his love to her.
He had always been passive before, but this time he must take the initiative.
He could not wait for her to come looking for him; he had to go to Da Ling.
