One of Us Is Lying (season 1)

The eponymous source material is not your typical tabloid romance, but a mixture of The Breakfast Club and an intriguing thriller: five students (by type - smart, athletic, beautiful, criminal, and outcast) come to serve their sentences after school, but one of them dies. Bad luck for the outcast, and part-time creator of the local rumor-sharing app: coincidentally, he was just planning to publish a jaundice on each of the four students, so everyone is suspected.
