This flashback depicted a 16-year-old Yiseon as a true \"sunshine,\" happy and surrounded by his friends (including the seemingly significant Yongjoon), which starkly contrasts his current trauma and survivor's guilt. The gut-wrenching imagery of him cradling a friend's corpse left many readers shattered. Amid the sorrow, the central power dynamic theory has evolved; readers now speculate that just as Yiseon's light can \"restore\" Hyeon's humanity, Hyeon's shadow abilities may be able to \"nullify\" Yiseon's trauma and prevent his suicide. This positions Hyeon as a potential \"sunshine protector,\" creating a new narrative of mutual healing and offering a sliver of hope against a seemingly inevitable tragic ending.","summary_source":"graph_aggregator","summary_status":"generated","summary_verification":"unverified"},"summary":"This chapter delivers a devastating emotional blow, confirming that Yiseon intends to use Hyeon's power to kill his friends and then himself to \"join them.\" This revelation has solidified the fan theory that the manga's title, \"Traces of the sun,\" is a direct and ominous foreshadowing of the fate of \"Yi-SUN.\" The community reacted with overwhelming heartbreak, amplified by a poignant flashback to eight years prior.
