Assuming you are talking about Ophelia from Shakespeare's Hamlet, here is my answer:
Some of her character traits:
She does not have a strong personality, she is
childlike , and naive, Innocent, and pure, very loyal to her family,obedient.
Although she loves Hamlet despise his cruelty, she obeys her
father when he tells her should see Hamlet no more.
Although se suffers intensively, she is not capable of defending herself,
and can not cope with the tragic events that unfold before her and
not being strong personality she goes insane.
Her innocence works against herself , she is the incorrupt and virtuous woman
( even if Hamlet does not think so!)
Her strongest personal quality is her honesty.
