So I kinda have two timelines as Light.
One follows the canon almost perfectly, expect that Near caught me a lot earlier because I got super careless after L died and didn't really care anymore.
---------------
The other one is one were I never find the notebook, but someone else does! I ended up joining the task force too and being really close with L. (It's basically the extra gay™ timeline).
We actually manages to catch Kira fairly quickly. Afterwards I keep working with L while still going to school, and is all in all a lot more pleasant than the other time line. Oh and I date L.
