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.

Nott, a handsome inventor lives in an all-boys apartment owned by Porpla, the yaoi fan owner. One day one of Nott's inventions causes an electrical fire destroying Porpla's Yaoi Cds. She decides to kick him out, when a new guy, Pun, an ad celebrity arrives seeking for a room. Knowing about Porpla's fondness for Yaoi, Nott asks Pun to help him stay in the apartment by pretending to be his boyfriend. Pun accepts and pretends to be Nott's boyfriend. But as time passes, the two can't help but eventually fall for each other.
