some mothers are Crazy about their sons... they don't want to be the "second place" woman to their son's girlfriends/partners so jealousy may be why!
I thought she just wanted their money and hated any other woman getting attention

old hag = grandmother = former princess = current kingś sister...
she is an stuck up b*tch who only sees people with royal blood as humans, everyone else (including nobles) are beneath her.
She even looked down on her husband the duke until they got married... grandpa/duke only agreed to the marriage cause he was BFF with her brother (the current king)
Anyway, grandma hates MC & ML MOM (her daughter-in-law cause sheś only a noble without any royal blood in her + grandma is so used to being in power and doing what she wants/entitled selfish person that only the king and her husband can stop her.
Her son (MC & bro DAD) was so used to being baby-ed by her that he is pretty useleass, he only know how to spend money and womanize... this Dead beat DAD was totally cheating on MC'& broś MOM and quickly lost interest in MOM- So despite being married into the family, MC & broś MOM had no real power in the family
Why did the old hag hate them ?
