You can ask your girlfriend if there is any program on the 7th on the evening of the 6th, then find an excuse to say that she is not available tomorrow, which makes her feel a little disappointed, and then go to her home early the next morning to surprise her, and then you can go shopping, sit or stroll in the place where you first dated, but you just said that you were going to buy water and ice cream and so on, and let her wait for you in the same place. Then, you will disappear for a while. You should worry her. When she is worried, she will come to you. This is what you should magically appear. Of course, you should bring a red rose to coax her. When she experienced two surprises, her mood should be difficult to calm down. At this time, you should take her shopping, eating and watching movies. Then you can go up the mountain and go halfway up the mountain from 2 to 3 o'clock. Then you walk slowly, and you say something disgusting, such as I will carry you for the rest of my life. When you get to the top of the mountain, you can take out a bunch of roses (98) and say: Send her 99 roses every Valentine's Day! Finally, take out a bottle of red wine and enjoy the beautiful sunset. If you want to send it, I think you can send some special stones to symbolize your eternal love for her. The seas run dry and the rocks crumble!
Some details, such as how to make red wine, can ask friends for help, hmm ~ ~ ~
And you can give her more surprises when you eat, such as asking monkeys for help when you go to the circus. It's up to you.
Finally, good luck! Ha ha!
