Light and Dark (Lawlight)

What if Light wasn't Kira?
What if he was framed?
//

When 17 year-old Light Yagami, an aspiring detective, gets asked by his father, Soichiro Yagami, chief of the NPA, to join the investigation on the 'Kira' case (AKA the case that involves criminals suddenly dying at the hands [or book] of the one who is known only as Kira), he gladly accepts. But what happens when all evidence and suspicion point to him when he has done nothing? And what can he do when he starts to fall for the world's greatest detective, L?

(L x Light, or Lawlight, although it doesn't happen until later chapters. trigger warning for chapter 17.)
