This is supposed to air this month, but maybe this got pushed back. I'd like to believe it's because "Jao Mae Asorapit" is doing so well now in the ratings, and I hope it has nothing to do with the Covid-19 outbreak.
(Here in the Philippines, all the dramas airing now are re-runs of old ones. Our production teams for both major networks are delivering episodes in a hand to mouth manner, hence they don't have any new episodes since we're all on a community quarantine for a month. I think Thailand doesn't have such issues, but this could affect future dramas if this pandemic persists.)
Haven't seen any post yet from One31, but according to this post in Pantip, the airing of this drama is delayed until May. When "Jao Mae Asorapit" ends, both "Bpai Hai Teung Duang Dao" and "Deja Vu" will air on an earlier timeslot, with "Bai Mai Tee Plid Plew" re-run replacing them (will be airing 4x a week).
