I Swear I'm a Good Student

Made for the phone in your hand, I Swear I'm a Good Student tells a revenge and mystery & plot twists story in portrait mode — no rotating, no black bars. Like most vertical dramas, it moves fast: short episodes, a cliffhanger at the end of each, and no filler. The plot, in short:

Elena, a mild-mannered student, secretly hunts sexual predators. She joins teacher Locke's art studio unaware he drugs and imprisons female students. Aided by his terrified girlfriend Wendy and Kate, who fakes insanity to find her trapped friend Millie, Elena drops her innocent act, exposes Locke at a national awards show, and sends him to prison.
