The Silent Guard (mxm)

Sometimes, words are not necessary.
Zen has been mute since the day he was born. Having grown up unwanted and on the streets, he unexpectedly found himself a hero in the prince of his country, Qi. The man had appeared when other children had been throwing stones at him, trying to drive him from the safety of the town's protective walls.
Qi ends up saving him, and as thanks, Zen decided to dedicate his life to protecting his master. Years later, as tensions begin to rise with one of their much-larger neighboring countries, he finds himself and his master thrown into unfamiliar territory, both physically, and mentally.
