***SPOILERS***
The grandpa is basically a prick from the moment he was introduced. He was trying to pit cousins against each other for power just so he could control them both. But basically he was using the lady to keep our mc in check because he had already decided the mc will be the heir because *gasp* he is a guy! Anyway he hired a guy to try and break up the main cp so the mc would marry a girl I guess. So they played to his tune all the while working in the shadows to gather evidence against the grandfather than reported him for money laundering and tax evasion.
Now I hope they actually end this with the grandfather choosing to retire or going to prison. I don’t want to read another cute story become annoying because it’s stretched out like chewing gum.
