Looks like the premiere of this won't push through on Monday. It appears that GMMTV will rerun dramas in the meantime - "The Sand Princess" for Mon-Tue timeslot and "Fabulous 30 The Series" for Wed-Thu timeslot. (Plus they'll be re-runing "The Gifted" and "The Gifted Graduation" this weekend.)
If this pushes through, new dramas are likely to air starting mid-February.
