Kekkon Shite Kudasai!
Omega went into heat and the alpha bit him and impregnated him. They actually liked each other but didn't know so the omega thought he used his heat to sesuce the alpha and ran away
Koubutsu wa Ichiban Saigo ni Hara no Naka
Omega wants children.
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 ?
Making a Child with a Beast
Uke saved a dog god when he was a kid and ever since then he has been disliked by all males. Now the god wants uke to carry his baby as a form of his gratitude.
