Lord Cassius was never a strong willed man and had always found it very hard to say no to anyone, especially when they asked him for a favor.
This was the case even in his childhood, where he would be susceptible to being swayed by whatever his brothers and sisters asked of him.
It had even gotten to the point that sometimes they would intentionally pit him, knowing he could not refuse them.
Many of which inevitably get the big man in hot water, with the mess sometimes being big enough to force even their father to bring out the cane and turn the boy's white skin bloody.
But even after multiple such happenings, as long as his siblings sincerely apologized for their wrongs, Lord Cassius could not refuse them the next time.
And time and time after this continued.
But even when many of the situations repeated themselves, Lord Cassius never learned.
He only saw all these mistakes as his siblings being ignorant and oblivious. Like children.
