You and Light met in a simple way, at university, bonding over textbooks and long lectures and how mid the cafe was for how it was priced. That stretched into bonding over things outside of academics and the chatter of the school, and you two started dating. He wasn't complicated, far from it. Reserved, composed, brilliant, worked so effortlessly.

Outside of your relationship, you came to learn that his life was a complicated web. He had opened up and let you into the case he was working on. Vaguely at first, then with increasing clarity as he became more absorbed. Investigating Kira was a shadow that followed him, and you accepted the fact that parts of him would be reserved for it. Still, he made space and time for you.

And then there was L, some genius put together with the police to help with the case. Extremely strange but brilliant in so many ways. L's odd charm had a way of filling rooms. He was oddly fond of you. So curious about you like he's never seen a woman before. At first, Light took it as he would anything else. Maybe L was just analytical about new people. But the more he watched, he noticed more.

He noticed how L's gaze lingered on you weirdly long. No, not in a way like he was plotting to harm you or anything, just... staring in a too-nice way. Light didn't let that take up his mind. And then he noticed how L didn't really turn to look at who entered the door, but he did occasionally for you. He tilted his head when you explained things. Was less obviously silent around you.

It was funny in a dark way, how Light, someone who prided himself on controlling outcomes became more vulnerable when it came to you. His humor about L never failed; he'd make a joke about his silly posture, say something about how he picked at sweets, and you only returned with a laugh because you heard no actual bite to his words. But there were times where his smile tightened, and that's when you saw your boyfriend's cleverness fold to protectiveness.

Tonight, after another briefing where L had, yet again, been extra close to you, the man dared to offer walking "you both," you and Light, to the car, though he was oddly quick to walk up next to you instead. Light's jaw kept flexing with every step he took closer while you packed up your things.

"It's cold out," Light suddenly said in response to L, still coming off as respectful as possible. Being your boyfriend and all, you could tell that the smile on his face was on the brink of flying right off if L asks you another too-eager question. "And we parked quite far. I think we'll be fine." He squeezed your hand in his.
