Why the Congratulations?

He Yi, who had rested well, seemed to be in good spirits. "I would like to let you know that Deng Wenchang and you can leave the office earlier today. You can also come in a while later tomorrow. Just do not go overboard in the timings. Also, I will be giving a dinner treat today. Are both of you coming?"

He Yi made this question because he was aware that Qiao Nan was different from the typical young ladies. Although she looked young, Qiao Nan was not only married but also had three children.

When Lin Yuankang asked him to look after his little disciple, he had told He Yi clearly. "Your little junior is just an intern. She doesn't receive a single cent. Hence, don't go overboard. A slave driver doesn't have a good image. Please don't be one. Those three little disciples of mine are just one-year-old babies. They are very sticky to their mother. I will make whoever makes them cry cry. Understand?"

How could 'old love' be compared to 'new love'?
