Heartbreak High
This Australian Netflix reboot covers the full arc of its 3-season, 24-episode run and is built around the sexual lives, relationship drama, substance use, and trauma of high school students. Nearly every category of mature content is present at moderate-to-strong levels throughout the series.
Older teens and adults only; Common Sense Media places it at 16+, and the content throughout the series supports that firmly.
