No he didn't care, every time the mother beat Tia to death in her room, he only warn Tia to never let that fact known to the outside world. What he mean by crossing the line is the mother beat Tia in front of other people. thus damaging his reputation.
i mean, after all, his only aim is to be an emperor.
He thinks Tia is marrying for him, there for he sides with her instead with their mother, and not because he sympathizes with his sister
yea its obvious, i just want him to also think it through you know. why would his sister do it for him when he has nvr done anything for her. he saying all that to the mother whilst doing the same thing. a hypocrite and a self centered lil bro.
lol why is the brother saying all that now. if he rly did care, he should have at least consoled his sister when ever she had to go through the mother.
