Homosexuality refers to a person's main sexual, psychological, and emotional interest in people of the same gender, regardless of whether such interest is revealed in explicit behavior. Those who have love, sex, or admiration for people of the same sex are called homosexuals. Homosexuality has experienced a development process from "crime" to "tolerance", which has certain historical and progressive significance. Hannah believes that whether you are gay or straight has nothing to do with sexual orientation. It only depends on whether the person you love happens to be not the opposite sex. If so, you are gay, and if not, you are straight.
