My take on that person is :
A. The person wants to share his feeling about beautiful life to others by writing the story. He/she has more to add to the story however before he/she completed the story, he/she ended his life.
or
B. The person have wishes and dreams about beautiful life which he/she didn't have so the story is written like that but it hurts so much so he/she took his/her own life.
I wanted to add hypocrisy but I think that's included in B.
My comment is just be honest to yourself ;).
