Summary
Ishigami Senku has always believed that his world is controllable, his emotions disposable, and his purpose absolute. Kohaku’s existence is built on loyalty. Their partnership is precious and unshakable, anchored by a trust that sustains them through war and science.
That stability is shattered when a brilliant rival triggers a fatal flaw in Senku’s reasoning: jealousy. Terrified by an emotion he can't dissect or dismiss, he makes a catastrophic error, pushing Kohaku away in a misguided attempt to restore order.
What follows is a descent into broken trust, psychological turmoil, and desperate self-sabotage. Senku, watching his perfect logic unravel, is forced to admit that the human heart doesn't follow the laws of physics. To survive, they must tear down the walls they built around themselves and risk everything on the most illogical, ten-billion-percent uncertain formula of all: love.
