Tan Heqian exhaled a lot, "I thought you were worried about something all day. Your husband is nine years older than you. He can take care of himself, you don't need to worry! I see you're so distracted all day, I'm worried about you too. If I had known it was just this matter, I wouldn't have wasted time with you in the library~ I would have gone to play ball!"
To Tan Heqian, He Zhilan's worry was just fussing over nothing. This is the difference between men and women. Women are detail-oriented and tend to overthink things, while men, like Tan Heqian, are carefree and do not let small things bother them.
However, though Tan Heqian spoke this way, his face did not show any sign of annoyance. He understood that women, well, they are like this. It also showed that He Zhilan and her husband must have a good relationship.
