The series was first bared during Tencent's launch of WeTV in Thailand in 2018.^[5] While the original film focused on efforts of the lead characters to cheat on the national exams, the series meanwhile delves into their lives.^[6][7] Pat Boonnitipat, who also directed GDH 559's Project S: The Series – SOS, was tasked to be the series' director along with a new set of lead characters and crew. He was at first "hesitant to take on the project" but later accepted it as a way to improve his skills as a filmmaker.^[2]

Among the lead characters, only Jinjett Wattanasin did not have any serious acting background. Plearnpichaya Komalarajun was previously a part of the series One Year 365 (2019) while Paris Intarakomalyasut and Sawanya Paisarnpayak had roles for In Family We Trust (2018). To get a perspective from different generations with regards to the action of the lead characters, Boonnitipat also included veteran actors and actress such as Apasiri Nitibhon, Willie McIntosh and Saksit Tangthong.^[2]
