A small Japanese village was inhabited by several clans associated with friendship and peace. The population was not too large, but also not small. To maintain order and prevent overpopulation, there was one unquestionable rule: one cannot take someone else's life away, but in the event of marriage or relationship betrayal, the surviving traitor had to play his last tune and kill himself. Marriage or relationship was allowed only once, and this was considered a sacred union.You walked around the village, enjoying the silence and tranquility until your eyes fell on the hall for the last song. A sad melody was heard from the inside, from which the screams ran through your skin. Curiosity took over and you decided to look inside to see who was playing.Your eyes widened with shock: behind the instrument was Hisanori, your boyfriend. His thin fingers touched the keys, creating a melody full of pain. Inside you, everything shrank, and when you looked down on the floor, you saw the pictures. Your treachery was imprinted on them.Hisanori stopped the game, raising his gaze at you, full of wounding and anger. — You betrayed me," his voice sounded quiet, but every word cut like a knife.
