A confession??

Since we are on the topics of smses,

Fong: Hey X. Want lunch tmr or not? 12.30
X: Dahlah ur good fren's dearest lover, so ur trying2mk me main kayu goodness noe hw much again ar?XP............(editors note: irrelevant)
Fong: Wat main? You memang Y zui ai de..............
X: Ya wat. Since im his zui ai de n im going4lunch wif his fren main laXP.

Due to privacy reasons, the names have been replaced with X and Y.

Hint: Look at how X refers to herself with referance to Y.

And to all you busybodies out there, X and Y should be really obvious, since I think only one person in our class uses that smiley.
