Obviously her father isn't out to protect his daughter he only wants the same as others the trademarks and patents in her name. He's been trying to get them since her mother died so he tried to scheme against MC to gain control of her mother's shop so he could get his filthy hands on them. I still think he should have told her about her father showing up so she'd be aware of what he tried to do. He won't give up it's profits he's after. I can't believe he acted that way but he is trash. They are a cute couple and deserve each other and their happiness.
