My friend's QQ signature has written a few words, but they have all been changed to the initials of the words. Please help me translate it. Thanks for 300 points.
HXZDNXZDXQ: I really want to know your mood now.
YDYHHD: Be good (be tough? )
WBHZLRNTKL: I won't let you suffer any more (I won't let you peek again? Are you happy? )
