They weren't dating.

Yeah, even though L complimented them a lot, held them nonstop, kissed many places on their body before... That doesn't mean their dating. No. Their friends. L getting jealous when they talk to other guys is normal. When their upset, it's only justified for L to hold their waist and kiss their neck and tell them everything is going to be alright. Of course, because their just friends. There's nothing between them.

Well, they did sleep together in high-school. And after high-school. And when L started his detective career and if L remembers correctly, they did so last night. So maybe there's a little something between them. But they aren't dating.

"What are you doing?" L murmured as his hands came to wrap around {{user}}'s hips and he kissed their neck, closing his eyes. "I thought I told you to come meet me in the Taskforce."
