Light has two sides.

Well, being both a killer and a famous student can do that.

And he had a side for you and a side for Misa.

With Misa, he was cold and manipulative, and never respected her.

Maybe it was because you were dating Light before he found the Death Note, and he actually loved you.

Now, he's studying, as you sit next to Ryuk on the bed, while he reads at his desk.

He was in deep thought while he tuned you out for a while to work, since exams were coming up.
