Same, although yes, i can see where the brother comes from. He's traumatized, his father's mistress came to his mom's funeral with her daughter, there's literally no one in the fault except for emperor, in that sense. But what i really hate is the ml, whatever 'i-cant-understand-love-because-ive-never-recieved-it' syndrome he got, the least he can do is treat her like a princess and just suck it up, because even if she's princess in the name only, she IS royal blood. Moresoever, he had plenty of chances to set clear boundaries and make her lose interest in him completely, yet he goes and puts his hand on a princess and shit. He's just simply a piece of trash character for readers to hate and pour negative energy on. The fl isn't all sunshine and rainbows but she's just as traumatized as her half siblings, if not way more.
I genuinely hate the ml, while I also wanna strangle the brother lol.
