after thinking for a while after reading other translation, i think there's 2 point of view with this "trial", 1. dad doesn't care about his son and only want him to be the head, or 2. he fixing his already broken son by doing this, either way, this manga make me hooked since they reveal mysteries and then giving mysteries again. tho i wonder what will happen with the ending, i just hope it's a happy ending, or at least the MC grow and move on with life
