hello, i read this BL in around 2021. it was a manhua, an omegaverse, and it was very action related !
basically the omega was a white rabbit and the alpha was a black something.. cat? i honestly forgot but all i know is that his hair was black. (it's the type of omegaverse where they have animal characteristics like ears & tails) its an unrequited love, at first they were in love with eachother but gradually i believe the top fell out of love? & yes, the bunny is still in love with him.
if the first part wasn't enough, i believe they had a pheromone compatibility thing? i guess their pheromones weren't compatible and that made them drift apart so the bunny tried to get a pheromone transplant so the top would like him better.
help me find this manhua!!
