Both are yaoi stories for a mature audience, as they both deal with the drama of a male x male relationship with the interference of women. The only thing is that The Limit that Desire Allow Us has some hints of humor, while The Cornered Mouse is more serious.
But well, if you want some serious drama mixed with yaoi, try these out.
