Omo, how could his parents do this?! How could they just drop this strange girl at his place and flee the country? Great... just great. It wasn't like he didn't have enough problems. And now? She just got added to the pile. Thanks, umma. Everything was explained so well in your short letter:

Jaejoong-ah,

Your appa and I found you the perfect girl! (yeah, perfect... who knows where she came from...) We have to leave the country for a while but don't worry, you are safe. (Safe? From what?) Xinling will take good care of you till we get back. (Like when did you ever take care of me? It was either the servants or I had to do it myself.) Don't you dare kick her out. We know what is best for you. (That is exactly what I'm going to do.)

Love,
umma

P.S. We registered her to the family as your wife so she wouldn't be deported. (What?!?! I'm going to...) Don't even try getting it nulled. There is nothing you can do. You know how powerful your appa is. Have fun!
