Boss Rattaket Santimahakul

In Srisaket, coach Man is the leader and caretaker of the Maitree Gospel Church, taking over after his parents passed away. Aside from his role as a leader in the church, coach Man is also a physical education teacher at the local high school and founded a water polo club at the school, which is made up entirely of Christians. The club members include Sawan, Champ, Touch, Poo, Yot, Petch, Kob, Me, Tao, Kem, Sun, and new member Lert. Also Cha, an alumni of the school, assists in coaching and helping out at the church.

This sequel continues from where 2 Moons 2 left off and will show the progression of all three returning couples. Pha has to persevere in times of helplessness as Wayo's incriminating pictures and videos have been released by Park and Pring. The story will show the progression of their relationship after that scenario. Ming and Kit will have to learn to develop and mature in their relationship, while Forth and Beam will also settle down and progress in theirs. Two new couples are also being included. Their storylines are more along the "rival to lovers" sort of scenario. One of the pairs includes Suthee, the medicine moon.
