Who is the constellation that mopes all day and destroys others' good mood inexplicably?

I think it's Pisces, because Pisces people like to fantasize, and they especially like to fantasize about unrealistic things, so once they find that reality is different from their fantasies, they are more prone to depression, they are sentimental and easily infect people around them.

In addition, Pisces people are simple and easy to trust others, but once they find that the person they trust has betrayed themselves, they will be very depressed and immersed in the shadow of betrayal.

Pisces people are especially careless. They may make many mistakes in their study and work. They will be particularly sad to find that they have done something wrong. They especially hate their carelessness, so carelessness is also the reason why they are unhappy.

Pisces people are particularly sensitive and afraid of trouble, so when there are signs of trouble around them, Pisces people get nervous. If someone is whispering around, Pisces people like to sit in the right place, and they will wonder if the other person is speaking ill of themselves.
