Moon Tae-il was found dead. Not just dead, but brutally murdered. Minji, Hanni, Danielle, Haerin, and Hyein: the five of them were best friends, bound by years of shared experiences and unspoken bonds. But beneath the surface, they were tangled in a web of lies, secrets, and unhealed wounds. Each of them had a motive-some buried deep in the past, others fresh and raw. The trauma of old betrayals, the scars of unresolved conflicts, and the weight of guilt pressed upon them, giving them each a reason to wish Tae-il out of the picture. As they struggle to unravel the truth behind his violent death, the lines between trust and suspicion blur. Were the clues pointing to one of them, or was there someone else hiding in the shadows, waiting for the perfect moment to strike? With every step they take toward the truth, they uncover darker secrets-secrets that threaten to tear their friendship apart. But one question keeps haunting them: Who killed Moon Tae-il? In this twisted tale of deception, power dynamics, and hidden desires, nothing is as it seems, and everyone is a suspect. Will they uncover the killer in time? Or will their own buried demons drag them deeper into a spiral of madness?
