Lets talk about complex in all in order to understand them all .
Complex comes from a person's unconscious mind, it's form by memories, needs, wishes, personal points of view All combined with emotions which goes around a curtain theme .
Sigmund Freud said "it will influence the individual's attitude and behavior." Towards someone or something.
And it goes like worshipping , admiring along with pure love to the thing or person
In psychology they say that whoever feels an x-complex may be feeling weak or not good enough or might be a sadist in life and sex or might feel like an Inferior Person .

A 'brother complex' doesn't necessarily have to equate love. Usually it refers to a possessiveness or protectiveness of a family member towards another family member without romantic connotations. The terms mother complex, brother complex, sister complex, and sometimes father complex are used in Japanese culture to refer to this type of possessiveness/protectiveness. This is just my own speculation and has no relation to how the term is used in Japan, but the term 'mother complex' might've come from the Freudian term 'Oedipus complex'.
can anyone tell me, whats the meaning of 'brother complex' is?
sorry if i'm wrong'-'
