Besides saying good night, I think there are still many things that can be said between lovers. As long as the other person is the person you want to say, then what you want to say is not just the word good night. Generally speaking, people nowadays are more naughty and promiscuous. When they say good night, they often use some funny or coquettish emoticons to express what they want to say, or send some earthy good night words, which will also leave a good impression on the other party.
Think of me when you can't sleep, don't waste your time. The moon is the coin I flip, no matter which side I want to see you. The moon meets the clouds, the flowers meet the wind. The night sky is beautiful tonight and I miss you again. The streetlight in front of your house makes me ask you if you want to come out and look at the stars. Go to sleep and close the moon for me. Forgive everything before going to bed, and don’t ask about the past when you wake up. It is said that putting sugar under your pillow will bring you sweet dreams. Don't close the windows tonight, I want to sneak into your dreams. I'm going to stay up late. When I'm done, I'll wake you up, boil the stars into syrup, soak them in the good night you said, and then eat them.
I'm sorry, I didn't have a chance to talk to you during the day, I can only wait until I send you a good night. But don’t underestimate these two words, they can accommodate the sunshine I see in the morning, the white clouds I see at noon, the breeze I encounter at night, and every word I want to say to you today, good night.
Actually, I think that for someone who can insist on saying good night to you, your position in his heart must be extraordinary. I think no matter what you say, it is not important. What is important is that you are here. The presence in his heart doesn't matter even if you don't say good night, as long as you care about each other, that's enough.
