Why the death note l finally died, and his real name.

You saw the movie version. L died because he wrote in the death note in advance and died peacefully in his sleep 23 days later. At this time, in order to prevent being killed by Kira before catching Kira, it also reflects L's determination to risk his life. Finally, I won, and we were moved and shed tears for his feat.

My real name is Lao Park Jung Su.
