The Collapse Began with His Marriage to Durandal

(Multiple female leads, logically consistent, pure romance is pure love, slow-burn, male NPCs will not appear unless necessary, the author is very aware of avoiding sensitive topics)

As the embers of the "Nexus," he possesses the wisdom to analyze all things, yet he carries the burden of a body that could collapse at any moment.

In order to continue the flame of life, he signed a life contract called "marriage" with Durandal, the strongest Valkyrie of Destiny.

At first, he only wanted to be the gentlest shadow behind her, paving the way for her with the wisdom of the stars.

But he calculated all the laws of the universe, yet he overlooked one thing—in this world full of regrets, "unreserved tenderness" is the most deadly temptation.
