Title: Hotaru Dies Tomorrow
Saneatsu is in love, but not with a real person. He's in love with the main character of his favorite novel, the somber and hypersexual Hotaru – a cat-eyed beauty with dusty pink hair. Every partner he's ever had has never been able to compare to her, resulting in Saneatsu being dumped over and over again. He's lonely, but he longs for Hotaru and no one else. To his surprise, he runs into a young man with cat eyes and dusty pink hair. He kisses the man before he can control himself and asks him out.
The man, to Saneatsu's surprise, agrees, and the two start an intensely sexual relationship – exactly what Saneatsu would expect from being with his beloved Hotaru. This Hotaru's name is Nao, and his entire personality, likes and dislikes, reactions, and commentary all align with his beloved Hotaru. This is everything Saneatsu could have ever wanted in a relationship. But is Hotaru really the one Saneatsu wants to be in a relationship with?
