Who was the first love rat constellation?

Among the twelve constellations, love rat, recognized as the first constellation, is Cancer Man. The scum of cancer men is sometimes caused by their ignorance of feelings, and they often hurt others unconsciously. At most, I can only realize that I have a good impression on each other and like to be with each other, but it is difficult to determine whether this feeling is love. Therefore, cancer men will hesitate and be very indecisive when facing their feelings.

On the other hand, the personality of the cancer man is also easy to give people the feeling of being a treasure mother man. Sometimes they have no opinions and need to be taken care of by others. In addition to these "scum" points, Cancer Man is sometimes a "central air conditioner", which is very gentleman to every girl and often gives people the illusion.
