Sennenkimatsu ni Hoeru Koi

Synopsis

The time is a world of warfare. Tenyou and Uru, who are as close as brothers or watchdogs, belong to an elite unit of a certain country. They lived together, fought together, and deepened their bond and love, but... their parting came suddenly. Uru died in enemy territory, leaving behind a promise and a kiss at the end of his life. Two years later, Tenyou lives on with his promise to Uru, and launches a surprise attack to defeat the enemy general, Kakezuki. However, when he looked back at Kakezuki's face, it was the same Uru he loved dearly. Who is Kakezuki? What happened to his lost love? A historical Chinese-style BL that runs through the court in the Middle Ages begins. (Source: cmoa, translated)
