The Ex-Morning follows two former lovers whose romance ended on a bitter note as they are brought to work together as "exes."
When Padtaphi, a top-tier reporter famously known as "Forecast Prince", loses his temper and throws hot coffee in the face of his junior reporter Tae, whom he doesn't get along with, Padtaphi is severely condemned by the public. His life turns upside down, going from rising star to fallen reporter, and his company immediately suspends Padtaphi and ends his role as a weather reporter to cool things down. Yong, a big producer who's Padtaphi's senior, gives him a chance to develop a fresh news program on the condition that he must work with a new producer, Tamtawan, who holds a degree from abroad and turns out to be Padtaphi's ex!
The two of them face many obstacles while working on the show together, from earning the trust of the crew that hates Padtaphi, to capturing the public's affection, and most importantly, winning each other's hearts. Can old flames reignite? Will this return to working together change them, or will they learn from this change together?
