A decade ago, Captain U-Jun Kang, an S-tier Esper, saw “Doc” sacrifice himself to save him—no doubt about it. He never even learned Doc’s name. Fast-forward to now, U-Jun’s staring down his new S-Tier Guide, Hui-Won Chae, who’s a dead ringer for the man he thought was gone. Hui-Won draws a complete blank on Captain Kang. Their paths haven’t crossed... or so he thinks. As far as he knows, he was out two months due to an accident. Will they connect the dots, or will this second chance slip away?
