Everyone in the Demon Slayer Corps knows that Sabito is fiercely devoted to Giyuu — but saying it out loud? That's another matter entirely. On Valentine's Day, with Sabito away on a mission, he works up the courage to send a string of voice messages, each one a shy, roundabout confession. What he doesn't know is that his rivals Sanemi and Obanai are sitting right next to Giyuu — and they have no intention of letting a single word land the way it was meant to. Twisted into something cruel, every sweet message becomes a fresh heartbreak. By the time Sabito races home through the night and finds Giyuu burning with fever, there's more than one kind of wound that needs healing.
