Parents need to know that Through My Window, a high school romance set in Barcelona, Spain and based on a book by Ariana Godoy, has swearing, drinking, and sex. The main characters embark on a flirtation involving teasing each other in a way that doesn't feel healthy or kind at the start. They have protected, consensual sex in a variety of places. There's kissing and hand jobs, oral sex, female masturbation, phone sex, an erection, a boy putting his hand up a girl's skirt at a party, a high school student said to be having an affair with a teacher, talk of virginity, and discussion of parental affairs. We see a man's naked bottom, a woman's bare chest and underwear, and naked bodies in bed in profile. A person is hospitalized after an allergic reaction. Teens drink heavily and at least one smokes regularly. Language in the English subtitles includes "f--k," "s--t," "bulls--t," "ass," "a--hole," "damnit," "witch," "idiot," "stupid," "jerk," and "God."
