Traces of the Sun — Chapter 4

Traces of the Sun Chapter 4 is where the story stops being quietly sad and starts getting uncomfortably tense, and fans felt it immediately. After the heavy reveal of Jeong Yi-seon living alongside the reanimated bodies of his fallen friends, this chapter brings Sa-hyeon directly into that private, rotting domestic space. He does not knock politely and wait to be invited in. He inserts himself, looks around, judges, provokes, and refuses to leave, turning Yi-seon’s fragile sanctuary into a battleground. From a character standpoint, this is a huge turning point for both leads. Yi-seon is established not just as traumatized, but as someone actively clinging to his guilt as a form of penance. He cleans, he talks, he coexists with death because letting go feels like betrayal. His restore ability, which should be miraculous, is framed here as a curse that traps him in an endless loop of failure. Sa-hyeon, on the other hand, fully leans into his role as the disruptor. He is observant, blunt to the point of cruelty, and completely uninterested in respecting boundaries. The chapter makes it clear his offer to kill the ghosts is not coming from pure kindness, but from calculation and a desire for control. Plot-wise, the chapter does not move forward with action or dungeon raids, but with psychological pressure. The contract hangs over every conversation, and Sa-hyeon uses Yi-seon’s home life as leverage to force a decision. Emotionally, the core theme is whether compassion should look gentle or brutal. Is it kinder to let a grieving person stay in his delusion, or to rip it away for his own good? Artistically, Do Hae-neul shines in the contrast between warm sunlight in Yi-seon’s apartment and the cold, decaying detail of his roommates. That visual clash sells the horror far better than any dialogue could.
