Before Chapter 27, here's what happens quickly (so the flow remains tight for readers and editors):
Chapter 25 – "Echo Within"Toshio begins hearing faint whispers through the mark. He believes it's Hana's soul trying to communicate, but the voice sometimes changes tone — gentle one moment, cold the next.
Chapter 26 – "Dream of the Red Moon"Toshio dreams of the shrine again, but this time the crescent mark on his wrist bleeds light into the dreamworld. He sees Hana chained under the moonlight, reaching out to him.When he wakes, his apartment wall bears a faint glowing rune in the same pattern — proving the dream is bleeding into reality.
