Musebinake, Junjou
Other than the fact that the seme was a man who murdered the uke's race as a mixed form of revenge and entertainment, this is a wholesome story about two people who are conflicted with race, but decide that they love each other beyond that barrier.

This would've been good as a longer series but the seme is a little kid which is unsettling.
My Purrfect Boss!
The author could have done more for world-building since the concept is broad and is easy to shape. As it currently is, it's nothing more than smutfest because the main lead has rocks for brains and the romantic interest is a pushover. This is currently a webtoon about a horrible yaoi trope which is disappointing since the art is neatly drawn.
