I received a text message from my birthday butler saying that someone checked my horoscope. What is this?

That is, someone used the "Fate Index" function of the Birthday Butler to calculate the fate relationship between you and him. I have used this function before, and it is quite accurate.

It’s your next birthday, butler, give it a try. Even if you don’t predict your horoscope, it’s very convenient to remember the birthday and give a gift.
