"What should you do if you love someone? What if you find that you have to kill him?" "I will kill him and complete the order. But I will leave with him." Because of that man, Sissel continued to live in the organization without seeing the light of day for more than ten years. Sissel vowed that one day he would personally end the man who harmed him. However, due to a strange combination of assassination attempts, he fell into a chess game - a game that he was destined to lose. "I lost." He smiled for the first time, but it was so exaggerated that tears couldn't stop falling, and sadness spread on his heartstrings. Looking at the still warm body lying in a pool of blood, he ended his life here. In this game, none of us won, but I got the only bargaining chip - your love.
