Death’s Warning: Solving Cases on a Countdown

The day I was murdered, I received a death countdown. The System prompted: "If you want to survive, find the real killer." I thought it was a prank, until the countdown reached zero and a cold blade pierced my heart. When I opened my eyes again, I was back one week before the murder. This time, the System issued a new mission: "Identify the real killer within seven days, or be erased forever." I stared at my phone. On the screen was a message from Shen Chuan, the senior I'd had a crush on for ten years: "Let's meet tonight." The System's warning flashed frantically: "Warning! The prime suspect has appeared!" This time, Chen Shun would trust no appearances. He would use his foreknowledge of the time loop to set an inescapable trap and tear away Shen Chuan's gentle, perfect facade with his own hands.
