This is a congratulatory gift for your return.”As soon as I was recognized as the lost granddaughter of the Namgoong family,I gained delicious food, fine clothes, gold and silver treasures, and a high-quality sword!I also gained a grandfather and a father who cried and laughed for me.But what was that strange, tingling feeling in my chest every time that happened?In order to protect the smiles of those I had once killed,and to preserve this warm and ticklish sensation for as long as I could,I was determined to change the bloody future that awaited me, unlike my previous life…**Namgoong Mucheon’s face darkened.‘Is this child truly raised to be an assassin?’The sharp killing intent and the sword techniques essential for an assassin were reflected in her life, as if they were embedded in her very being.‘Damn brat.’Anger surged within Namgoong Mucheon.He restrained himself from cursing aloud in front of his granddaughter, muttering in his mind instead.‘How dare they raise my granddaughter as an assassin?’The blue energy surrounding Namgoong Mucheon grew even stronger.
