Poor lovesick Natsu has been crushing hard on a male coworker of his for ages now, but he knows it isn’t meant to be. If he didn’t already feel like the universe was playing a sick prank on him, he definitely does once a mysterious stranger with dog ears and a tail – named Kuro, like his jet-black hair (fur?) – shows up at his doorstep asking for his hand in marriage. Natsu’s not quite ready to move on from his unrequited longings, but this loyal dog is willing to wait as long as it takes for his master to come around.
