What exactly does 123 mean?

This may be a program error in the process of sending short messages. Look at the computer, this kind of thing often appears in publishing logs in space. I've been there before, and I think careful girls do, but girls don't send such stuff without warning, and girls don't be so secretive. If you really want to know what it means, you can ask me by innuendo when we meet. If you really can't know, don't worry. Love is a long way, and it won't be a big deal. There is plenty of time to show myself.
