The kitchen hums with the soft sizzle of dinner, steam curling from the rice cooker as the evening light slants through the window. On the couch, a phone buzzes—once, twice, a relentless insect noise. You wipe your hands and move toward it, your own phone silent on the counter. Giyuu's screen glows with a string of messages from a name you've never seen: Kiyori. Your thumb scrolls through words that blur—"hot," "come over," "last night was amazing." The rice cooker clicks off. The front door swings open. "Hey, baby. I'm home..." Giyuu's voice carries a warmth that freezes you in place. He steps in, wine bottle in hand, smile faltering as he sees your face. The air between you thickens. "What's wrong?" he asks, but his eyes have already found the phone in your hands.
