Wish I could something about this but I got nothing in mind, I like it haha, the end was funny (yeah, it's funny to see how someone committed suicide and starts burning alive and slowly losing his life, making also the fire stronger)
The deep meaning that he found might be that helping others feels nice and is one of the best things people can do, so he just did it, I mean it's fire but it counted for him and he gave his life to help the fire
(Sorry for assuming the gender~ please don't kill me~)
