Heartstopper

Main characters Charlie and Nick are both White; several of their friends are people of color. Charlie is gay, and Nick is bisexual. Their fellow students (as well as the teachers at school) are of many different races, ages, body types/sizes, sexual identities, gender identities, and ethnicities. One important character is transgender; another is asexual. A minor character uses a wheelchair.

In one episode, Charlie is subject to sexual violence at the hands of a "boyfriend" who kisses him and pushes him up against a wall as Charlie says "Stop!" Charlie was also subject to bullying; we see him pictured in a dark room as critical messages appear on-screen (i.e. Charlie was "asking for it," and someone says they'd "rather be dead than gay"). Arguments/sharp words.

Lots of romance, flirting, kissing, dating. More attention is paid to feelings than sex, and romance largely consists of gentle kissing and hand-holding, but there are some passionate embraces (one leading to a prominent hickey) and the suggestion that sex might happen, but nothing graphic is discussed or shown. Teens who are dating lie in bed together with their clothes on. It's implied that two teachers have a sexual hook-up.

Some use of "s--t" and "d--k." British slang: "knob," "piss off." The word "ass" appears in a text, and "f-g" is used.

Teens at a party hold plastic cups, but it's not shown what they're drinking, and no one acts drunk. During a school trip, teens have a large hotel room party and pour each other big drinks; at least one character drinks to the point of getting sick.
