The Drowning of The Daffodils

Author's note: I'm trying to write a fictional story, I have many ideas but I haven't put the pieces together yet. I've decided to document (a limited amount of) my progress and leave it open for feedback & suggestions. I have a clear idea for the plot, so here's a brief description:

Have you ever just felt your mind go blank, silent. Become disconnected from the world for a moment, lost in your subconscious, trapped and isolated in your own mind, left alone with that one consuming thought; Why? "Why am I here?" "Why don't I know the reason?" "Why don't I have any answers?" "Why does everything happen?"
During adolescence, as our brains grow, develop and begin to absorb the world around us, we will inevitably reach an age of consciousness. And eventually, an age where we gain an understanding of our existence and the concept of life, death, and the 7 billion people we don't know coexisting in the same planet we are... and our lack of knowledge as to why any of it is real or possible. As humans, it is natural to question our surroundings, wonder why we're so ignorant of it all and seek out an answer. But these thoughts typically don't linger in our minds when we are happy and simply living life without over-thinking. We tend to ponder these questions in times of grief, guilt, or regret. But for some people, the thought crosses their mind every day.
Evan wasn't like most high-schoolers, or most people for that matter... Neither was Iris. Evan was full of thoughts and ideas that he never verbally expressed. He hated parties, high school and all the selfish, mindless, social-climbing villains in it. He tried to stay away from most people, but for the first time during his senior year, he becomes strangely fascinated in an artist/writer called Iris. They bond over their mutual habit of over-thinking, passions and addictions. Immediately enchanted by her depth, intelligence and unique talents, Evan fixates on an unrealistic idea of Iris as an perfect human being.
