In a world ravaged by the sudden appearance of dungeons, "Awakeners" are the only ones capable of fighting back, while "Restorers" like Jeong Yi-seon are tasked with rebuilding what remains. As the only S-class Restorer, Yi-seon was once a celebrated hero, but a catastrophic incident in a high-level dungeon left him the sole survivor and a broken man. Now, he is haunted by the "traces" of his deceased friends—undead remnants that tie him to his trauma and prevent him from moving forward. He lives in self-imposed exile, hoping to fade away along with his memories.
His isolation is shattered by Sa-hyeon, the leader of the elite Chord guild and a top-tier S-class Hunter known for his chilling efficiency. Sa-hyeon doesn't just want Yi-seon’s restoration powers for his team; he offers a deal that Yi-seon cannot refuse: "I can help you kill your friends." By promising to eliminate the supernatural burdens that haunt Yi-seon, Sa-hyeon draws him back into the dangerous world of dungeon raiding and into a complex, transactional relationship that oscillates between manipulation and genuine care.
Traces of the Sun is a compelling psychological BL drama that masterfully blends high-stakes action with a deep exploration of survivor's guilt and PTSD. Readers will be drawn in by the intense chemistry between the two leads and the mystery surrounding Sa-hyeon’s true motives. It is a story about finding the strength to let go of the past, even when the person helping you is as dangerous as the monsters you're fighting.
