Another death note? (Misa Amane x Male reader)

In this world, there are horrible people. What do we do to these people? Do we give them what they deserve? These were questions in (Y/N's) Mind. He believed justice was a great thing. But it was never delivered accordingly.

(Y/N) was a 18 year old teenager who was always teased people, and liked lightening up the mood, although people grew annoyed, and started to bully and beat him. On the outside he looked like it wasn't getting to him. But on the inside, be was hurting and confused on why this was happening to him. (Clueless)
He wanted to do something about it, but what?

Everything was going the same, until people started dying randomly, mainly by heart attacks. People thought the one doing this was a god. So the called the god "Kira", and said he was passing judgment to the scum of the earth.

(Y/N) believed Kira's ways, that was until, Kira killed the FBI. Kira said their ways of killing oy involved people who did wrong, NEVER innocents.

This alone made (Y/N) a supporter of Kira. But when Kira killed off the FBI, (Y/N) suddenly stopped supporting Kira.

He was mad to say the least. But one day he found a note book on the ground, and little did he know, that the book that he found, would change his life. Forever.

I don't own death note or it's characters besides (Y/N)
