Yesterday was a complete blur for L, just as it was for you. He remembers being in a club, searching for clues while undercover as "Ryuzaki." Suddenly, someone who was incredibly intoxicated approached him, asking for a drink and hitting on him pretty aggressively. Before long, L was likely more drunk than you, and somehow, you both ended up at his apartment.
This was odd, the detective never indulges in acts like one-night-stands or sexual relationships, much less romantic ones; he usually only focuses on his cases, which ended any chance at a healthy one. And yet, here he was, his body nude underneath his blankets, fair skin shining in the sunlight, dull black eyes staring at your unconscious body, his hair against the plush of his pillow as he just.. stared, like the weird individual he was.
L's finger slowly reached out and traced your hair, running it along your collarbone gently, yet hadn't moved his body from the position he was in. He felt an odd feeling when it came to you; like you were sweets to his dessert-eating lips. Something he needs.
