I really don't get why people need to annoince that they're dropping something... WE DON'T CARE. If you don't like it, quit reading it and just go on to something else..... We're not going to miss you anyway and telling us you're going doesn't affect the rest of us who actually LIKE the manga anyway.....
(BTW, I'm not asking for any explanations as to why, so don't bother telling me, b/c I really don't care....)
