Pff most people don't care as long as they get to see some kawaii guys making out, so don't worry about deterring anyone with your story.
I have to give you props for drawing your main actually looking malnourished, most people are too scared to make their characters look unattractive, and normally throw a couple lines on the face to indicate "sickness". Also your art is pretty solid, good job!
Good luck with your project!
