Kinda funky pacing. Chunks of time were skipped, which took away from the potential to really get you in the heart, but the art was nice and who am I to tell you that you can't sleep with your fictional cousin.
The story: University student Miya lives with an incurable disease that will likely kill him in his early 20s. He spots a flashy man in the university's library one afternoon and is surprised to discover the man, Rei, is actually his cousin who used to visit him in the hospital as children. But even more surprising is that Rei has an interest in biology and in Miya's disease, which he claims to be able to cure.
