thank you so much, oh my god. this made my day!! i’m really glad you find it unlike other typical wattpad fan fictions, i really didn’t think it would get quite as popular as it did.
you see, Jeongguk and Namjoon are friends in real life. it just so happened that Jeongguk, who is ‘JK’, is being investigated by Namjoon himself (hence why he’s always a step ahead of Namjoon). but Namjoon heard Jeongguk’s voice not as JK but as his friend Jeongguk, and therefore Namjoon sees no connection between the serial killer and his friend!!
