Long ago, the fandom had collectively decided that L and Light shared a bed during the Yotsuba arc and now I'm here for it
Here I offer you Light sharing the bed with a kicking overgrown shrimp man [affectionate] (not a very idyllic experience for Light overall, let's face it)
It's not even that funny of a joke considering how broken your humor is, it was just an image macro that had been shared on the internet for a while. Was it even witty? Silly, of course but there's L, right beside you, shoulders bouncing from a laughter he's trying to conceal. He has a hand loosely covering his mouth in his fit of giggles, the corners of his eyes creasing as he looks at you.
"Please... Y/N, could you say that again?"
Chewing on your lip, you face the screen of your phone to show him the image macro again and in the fakest Australian accent, you say,
"Smork Alam."
He bursts into gleeful laughter while hugging his knees, and you just realize it's a sound you want to keep hearing from him as often as possible.
