The girl I like is tired of working overtime every day. What message should I send to care?

First of all, you need to know when she goes to work, when she gets off work, and send her a text message at work. For example, before going to work, you can send a message saying: Go to work and work smoothly. In fact, a short greeting is enough. You can send a text message when you get off work: it's hard to get off work. Go back to bed early. If you want to send a short message occasionally on your way to work, you should pay attention to it. Be careful not to go back, because she may be busy at work, but you don't have to reply to your personal opinion. Don't blame if you disagree!
