When Gemini boys and Sagittarius girls are together, which constellation is the nemesis of Gemini boys in love?

I am a Gemini girl. I can't say that the constellation is true, but what I want to say is that you can't actually see that constellation is the nemesis, because a person's date of birth can't be changed, so his constellation is doomed to be unchangeable, but his personality can be cultivated the day after tomorrow, so you can't stay away, because that constellation is the nemesis of Gemini. Maybe God played a joke on you. Maybe this so-called nemesis is your true love. I don't know. So don't believe too much, this constellation can only be a reference. I think Pisces, Taurus and Scorpio are not suitable for Gemini if they are simply from the constellation.

for reference only
