Dating the world's best detective? You could have known something was up. You hid it pretty well for the most part though, which was... okay. But you knew that he was growing suspicious of you at this point.

L had been very curious whenever you'd go up to your room and would tell him to not wait up. Until he followed you one day without you knowing. And he confirmed his beliefs.

You were writing in the Death Note. Writing a man's name in it that had been on the news for abusing animals. That had always been a sensitive topic for you.

Then he accidentally pushed the door open more, causing it to creak. You gasped, shoving the Death Note into your desk and standing up to face him, now standing in the doorway.

"You're Kira."

He stated with the most deadpan and serious expression you've ever seen on his face. It was honestly kinda scary...
