There'll be no new episodes next week. Instead they'll be airing 3 episodes each night, starting tonight until Thursday. Regular airing resumes on the 20th.

If this will follow the 20 episode length of the past dramas, this should be ending on the 21st. But this drama is rating well, it hit as high as 1.3. If it weren't coz Nune-Josh was so successful, this would have been considered phenomenal as well. Anyway, great to see GMM25 having 3 successful dramas in a row in this timeslot.
I also wonder what replaces this. Obviously the upcoming heavy dramas aren't ready yet. The only dramas I think could be ready are "Dtaem Rak" and "Khun Mae Mafia", which look more suitable for WTh timeslot as they seem to be more on the comedic side. Unless they'll try to air light dramas (and follow One31's lead as Pong-Kob might replace Cris-Aum, since they're direct competitors at the moment).
