Please, Marry Me!!
Love Joto!
@ch 3.5 Uke and seme are rivals from delinquent groups. Uke keeps challenging seme and seme likes uke, thinks he is cute.
Amanojaku ni Koishite!
Yokai uke can only say the opposite of what he means. Seme likes how cute he is even though everyone is offended by him.
Sono Koi ni wa Wake ga Aru
Uke is cute but violent in an all boys school because he always gets hit on. Doesn't like most people because he knows they just think he is cute. Starts hanging out with seme in an animal club because seme doesn't chase after him and bother him like other people.

@ch 3 Uke and seme are a couple living together.
My Purrfect Boss!
@ch 38.5 Seme is a new intern at a company. Uke is the boss but is special and has cat ears which only a small part of the population has. Seme is always straightforward and naive with his actions, making dumb mistakes. His unaware actions sometimes catches uke off guard. Ends up going on a work trip together when uke gets his heat. Later both uke and seme begin dating but uke's past toxic relationship goes to the company too.
Pheromoholic
@ch 9.5 (2nd season) Uke is a sea rabbit and seme is a lion chimera. Both clans are not suited for each other since lion preys on the sea rabbits based on a legend. Both uke and seme are models and end up working together once seme transferred over. Uke didn't like anybody and his heat/inability to resist lion clan, so he took meds all the time, but comes to love seme. Uke's clan doesn't approve because of past history, but seme does research himself and ends up finding out that it's the lion clan that's in danger that's why they avoided each other.
