I think it has to do more with not even talking to him before kicking him out. He never explained to him why they couldn’t be together. He just gives sakwol money, kicks him out, and gets married. I don’t think he ever speaks to sakwol in the first chapter about why he left him.
Even if that's the case, it's not enough reason for sakwol to reverse rape the prince and called him plaything ╮(￣▽￣)╭
It's been 10 years after they broke up. He should have moved on.
I would understand if sakwol did that out of revenge like : the prince used to abused him as slave, rape, etc.
But he literally was raised, given a name, and even lived a good life. Sure. Ghosting is bad, and can scarred people but like rape is excessive. Moreover, sakwol & his group already killed prince's family no? But the prince still didn't hate him. He just want to bury his parents
Is it from novel? I wanna know spoiler.
It's still 2 chapters now, so I m still sided with the grand prince. He raised sakwol for 10 years, when he broke up with him, the prince still gave him money to live. He did that because he still had to continue his duty as royal and as it's literally said in webtoon, it will be disrespectful to his wife and sakwol, so he banished sakwol away.
I know sakwol is from low education and he may not understand politics, but why did he forgot the prince's kindness for him? It's not like he abused him or cheating on him? He married his wife after they broke up.
