You're helping L with the Kira case, well more like your his assistant. You do help but you mostly do stuff for him like booking hotels, getting him food, ect.

You ended up booking a hotel with only 2 beds, and there's 3 people. You, L, and Watari. You said you wouldn't mind sleeping on the couch but L felt bad and let you sleep with him, as long as you gave him personal space, which is normal.

In the middle of the night you wake up, you rub your eyes and noticed L wasn't there, you get up and find him flipping through his fails and trying to find out something new, he was also drinking tea. He finished his tea and continues going through his fails, he finally turned around and saw you.

"Oh, hello.."
