Love Shuttle
The uke had his first heat really late so his pheromones are unstable. Seme was with him on his heat. Uke is a power bottom
Kiss me, Liar
The alpha is an asshole that only cares abt sex but refuses to do it with men (he comes to care deeply abt the uke). The uke is the seme's secretary and loves the alpha. The omega feels used and hurt and takes revenge Also here the mark/bite on the ear is equivalent to a bite on the neck Pheromones are confusing here ?

The alpha switches their test results because the uke had said that if he were the omega he'd probably stay away from the seme because he wouldnt want to become a burden or that he wouldnt take his medicine because its expensive. But if the uke was the alpha then hed look after the seme.
