The Waning Moon Sinks into the Abyss

[Two male leads + political scheming + yandere + possessive love]

One is a gifted young noble whose fame once spread far and wide, until he abandoned his writing brush for the battlefield. No one knows that beneath his glorious military record lies a frail, ailing body.

The other is a noble born into a life of luxury, yet beset by misfortune. No one knows the hardship and bitterness behind his eventual rise to the throne.

The world is vast and boundless. They press upstream, filled with unease and uncertain what lies ahead...

As his only living relative, one offers wholehearted devotion and risks his life to protect him. Having endured countless hardships, the other remains suspicious and hesitant, unable to decide whether to trust him. The brilliant young man pours his heart and soul into the relationship, only to watch the child he once knew lose his innocence and forget his original aspirations...

They face life and death together, supporting one another through every hardship, but is the warmth between them true, or false?

Across past and present lives, after countless doubts and deliberations, they finally try to put their entanglements behind them and cherish the bond they share.

But one arrives too late. In the end, both are destroyed: one loses his life, while the other descends into madness...

Can such an ending be changed?
