First of all, I think it must be Scorpio. They say that Scorpio is a mysterious constellation. He won't open his heart easily and let others know deeply. He is very insecure, so he often disguises himself and then prevents others from discovering his true self. He always pretends to be strong, but he also has a weak side.
Aquarius is not only an Aquarius, but also likes to protect her happiness. She is afraid that she will be hurt and her inner tenderness will be disturbed by others, so she always pretends to make herself stronger, so as not to let others find his inner softness and that kind of sad place, so she always plays herself into a role she doesn't know and doesn't let others know her.
There is another one, I think it is Capricorn. We finally became a person who likes to disguise ourselves very much. He doesn't like others to read his mind. He always wants to pretend to be profound. If someone sees through his new machine, he will feel helpless and even flustered, so he will always pretend to be himself and let others think that he is a powerful or capable person. In fact, their loneliness and meatballs are unknown to others.
