I think any constellation is possible.
For example, the article is Cancer, Dānlín is Libra, and Chen Sicheng is Pisces. Every constellation has an affair, whether it's a man or a woman, it's the same.
Love rat has no national boundaries, and love rat has no constellations. Any constellation will appear.
In fact, the constellation is not omnipotent, and the constellation can't predict everything at all. Predicting love rat like this is totally unreliable.
If someone asks, which constellation is the most loyal to love, or which constellation will never cheat. If someone says that a certain constellation is like this. Then, you can search online, Cancer cheating, Virgo cheating, Aries cheating, 12 constellation. I believe that after reading it, you will doubt whether these constellations are accurate or not.
You know, everyone is an independent individual. If a constellation is prone to love rat, what is the probability? Is it 99% or 1%? If there is no data to prove it, how can we believe that this constellation is really prone to love rat?
People casually say that a certain constellation is prone to love rat. Why should we believe him? If the constellations are so smart, why should we search which constellations are the most loyal and which ones are derailed?
So, don't think too much. Constellations cannot predict love rat at all.
