The Next Erased Title for Security Reasons

In the backdrop of a war that threatened to tear apart the life of many:
A kidnapped princess, a seven year old spy, a conniving regent and a prince, a foolhardy king, and an inexperienced assassin.
The mastermind puppeteer behind the war seems cold, distant, and untouchable. But when he 'survives' an assassination attempt, he gives himself to the young assassin.
Three nations, one War. Treachery, fear and fate: it all threads through the fingers of one man; one ruthless man whose presence could alter anything.

HIGHEST: #60 in Fantasy

Note: After a few chapters, the main narrative turns BL.
