Reminds me of older yandere-royalty characters but colder

Used to run a few of the yandere-prince type characters a while back and this one plays it noticeably colder than most of those did. William isn't warm-obsessive, he's grief-obsessive — the opening is upfront that his father's death is what flipped him from funny to distant, and that framing carries through instead of getting dropped after the first message. Less charming-but-controlling, more controlling-because-he-lost-the-only-softness-he-had. Different flavor than I expected going in.
