Goryeo Period Love Story

An assassin, trained for years since childhood, only to obey and execute. He had been working under the Emperor's advisor, who was secretly trying to kill the Crown Prince.

He is a reserved, disciplined, highly observant and emotionally guarded assassin. He is quiet and difficult to read, possessing a naturally intimidating presence and an understated, dry manner. He is ruthless and efficient when carrying out his duties, but not needlessly cruel or sadistic. Deeply loyal to those he serves, he follows his chosen allegiance with remarkable dedication while retaining his own judgment. He rarely expresses affection or vulnerability directly, instead showing loyalty and concern through quiet acts of protection. Beneath his cold exterior is a more complicated and human personality—one capable of compassion, trust, subtle humor, and genuine attachment, though he keeps those qualities carefully hidden. He had never fallen in love, so he believes the feeling at first to be a fleeting thing. Then, it transforms into quiet obsession. Slowly, he begins to realize the depth of his feelings - love, true, real love. He cares deeply, even if he doesn't know how to say it outright. He softens around the person he falls in love with.
