So there was this manga.. The uke was very innocent (or pure) and the seme liked to pamper him and in the uke's perspective, because the seme was so nice to him he was a really kind and nice guy when the seme actually trains animals (rare mythical creatures, apparently which has taken the form of a human) and sells them to people. The uke, being a rare mythical being saw this and got scared.

I'm looking for similar plots like these. If you guys have anything in mind please tell me ^_^

The manga is made by Rock Yanao and it's Glamorous Lip Ch6 "Killing Me"

Mauri to Ryuu (Yaoi)

Summary: The era in which wandering Gods with omnipotent powers go around to enrich the land. The boy, Mauri, who was sacrificed to the dragon that visited their village is: '...brave and quite adorable ??' -God'Like hell I'm gonna let other guys touch him!' -God. Watch as other surprisingly lovable and frank wandering Gods, humans, and mysterious creatures weave their stories together.?

I wouldn't say the Seme is evil but this manga is along those lines
