Who has the longest love among the twelve constellations? Why doesn't it have Libra?

Libra is a very misleading constellation. Because of the pursuit of balance,

Hesitation is Libra's weakness and emotional characteristics, which means Libra always subconsciously pursues a shadow in her heart, and her appearance will be constantly compared when she is in love with others, and she will be ambiguous with many people, and her personality will also be affected by it.

The reason is that it is hot and cold, and it is uncertain. So in the eyes of people in other constellations, this is a playboy, and many people decide to leave because they can't accept Libra. So many relationships with Libra are hard to last ... Sorry, of course, if Libra meets her/him.

(Forgive my tacky ...), it can be said to be a very specific constellation, but fewer people can see this side.
