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.
