Any chinese drama wherein ML and FL broke up and then reunited later as co-workers?

I know a Korean drama, if it helps. 

It's called cunning single lady. 

You might also like my secret Romance. 

 ✔️ My Secret Romance 

✔️ Refresh Man 

chinese drama with that somewhat hasthe leads working together, yet they are not really coworkers plot:

  • My sunshine
  • Autumn Concerto (taiwanese)


But here are addition dramas of that plot, but not chinese:

  • Discovery of Romance
  • Beauty or Beast
  • Wild Chives and Soy Bean Soup: 12 years reunion

i think Here to Heart has the female lead works as the male lead secretary, but i'm not sure if they're a couple before.

Here to Heart, they were a couple but broke up. And seven years later she becomes his secretary. 

Remember the Son is like that, but is a korean drama
