I didn’t get that either.. I went back and read it but maybe she was alluding that someone close to her has died before (but not from her past life, I don’t remember there being anyone like that) or that she’s almost died before (from the assassination attempt)
The colours of the title have always indicated when the chapter will have smut but we didn't see anything for this one. So I don't think Mr Cha only watched MC sleep... (⊙…⊙ )
The real question is : Season 2 when ?!
