Well what i understood so far it that our MC(Nan qui) who is originally from an omegaverse world ( he was a recessive omega with special trait where other's pheromones doesn't work on him) transmigrated into a novel where he becomes the elder disciple (supporting character) of the same master as the novel's protagonist, and that their master(most probably the ML) spoiled the novel's mc in the novel and died early so he became the ogMC's "white moonlight".
And since the ogMC got regressed back or reborn (whichever one it is) to before their master's death he want's to save him.
Also the master (ML‽) somethings get get controlled by his heart demon (most probably on full moon days just guessing the time(￣∇￣")) and during this time he can't speak and does 18+ stuffs with our MC and then forgets about it when he is back to normal (curse him for that (︶︿︶)＝凸).
Ok.. Thank you （☆/＞u＜/）
Can somebody explain the storyline up till now?
