After spending ten years drinking ice and sleeping in a drug den, he came back as a "traitor."
When his past merits were stolen and his comrades turned on each other, he used his body as bait in a desperate situation to gain a glimmer of life.
After being seriously injured and comatose, a forced memory retrieval broadcast live to the whole country completely exposed his buried ten-year undercover career - those misinterpreted "betrayals" were all the silent perseverance of a lonely hero; the "hero" wearing a medal turned out to be a double-faced ghost who stole glory.
Memory is a blade that reveals the most extreme loyalty and the most despicable betrayal. When the truth is revealed, the hero's life is like a candle in the wind.
