The series was announced during the GMMTV Riding the Wave event on 26 November 2024. In a press interview after the event, Director Aof Noppharnach shared that he was waiting for the right moment to pitch the idea for this series to Gemini and Fourth, following their collaboration in
Moonlight Chicken (2023). Director Aof stated that he was inspired to create this series with the intention to open up a conversation around the relationship between religion, faith and love. He also shared that he travelled to different churches around Rome to gather inspiration for the series. Author Kittisak Kongka (Best) shared that the
Ticket to Heaven novel and the series would not be entirely identical. He and director Aof first came up with the idea of the plot together, which he then took to write the novel, a process which took several months. During that time, he and the director also continued to develop the script for the series, resulting in revisions that differ from the novel. Fitting photos for the series were released on 26 February 2026, revealing additional cast members including Oliver Poupart (An), Peerakan Teawsuwan (Ashi), Poon Sutarom (Pun), Phakawat Tangchatkeaw (Tor) and Supakorn Kantanit (Guitar). A
read-through with the cast was held on 28 February 2026. In March 2026, it was announced that the series had completed its workshop phase. == Marketing ==
