I really need to catch up on XXXholic. I'm reading Spellbound as well (though as usual, I end up wanting to hit at least three of the characters and yelling "DO SOMETHING ABOUT IT!")

Urgh, Rumbling Hearts? That has to be the angstiest anime series I have EVER seen. Seriously, I remember watching it when it first came out in Japan (in my university anime society) and being completely amazed at just how depressing it was. Just when I thought it couldn't get any worse, it would. Frankly, I'm amazed that no one had died by the end.
