I Don't Want To Drown Only In You
Aoi has been sleeping with his alpha childhood friend for a while now. It doesn't help that they work together too. But he has very clearly drawn a line for friends with benefits. But then he starts feeling weird and it turns out that he has turned into an omega
Romance, But Not Romantic
Kinda a hate to love scenario, omega does put money into a "hitman for hire" savings account when the alpha pisses him off. At a software company, Jinha is so stressed and overworked that he turns into a recessive omega from a beta. Now he has to figure out how to deal with his own pheromones and everyone else's too. And they all make him nauseous except for the team leader Cha's refreshing pine scent. So he starts leaning on him for help, even if before this he never liked the alpha much at all (see above hitman for hire).
I Like Your Pheromones
Super cute. A beta turns into an omega late and develops an allergic reaction to alpha pheromones. Except for the alpha in his class who has stolen the hearts of all his crushes by being good at everything. This feisty little omega refuses to be outdone by the cool and top student alpha. Mostly a school drama with some omega elements
