Since the late first madam of the Situ family did not want her sons to have anything to do with the rest of the children of the Situ family she has kept them close to her in the manor at the back of the Situ mansion which was now abandoned while being rumoured as the cursed manor. But then the first madam died and the three hell-raisers were brought to the main mansion by her father.
They might have been twelve or thirteen with the eldest master in his fourteenth year. In the year when their mother died and they arrived at the main mansion, her mother warned her not to approach them since the three young masters were not like other children but it was not in Situ Zhilan's personality to leave her opponents alone without getting to know them better.
