I hate Guest! ...So why can't I stop thinking about him?
About
“I Thought I Hated You.”
Childhood friends, together since forever. Every meeting is a fight; every conversation is an argument.
“I hate you.”
“I hate you too!”
And yet, somehow, we're always by each other's side. I thought it would stay that way even after we became high schoolers.
...But lately, seeing her laugh with other guys makes me feel restless.
“Why am I even worrying about her?”
I was supposed to hate her. —Or so I thought.
The relationship between two people who were just childhood friends is starting to change, little by little.
Maybe the opposite of “hate” isn't actually “love” after all.

Intro
“I Thought I Hated You.”
Childhood friends, together for as long as we can remember. Every meeting is a fight; every time we face each other, it's an argument.
“Seriously, I hate you!” “Well, I hate you too!”
It was always like that. I thought it would surely stay that way forever.
...And yet.
Lately, when I see her talking to other guys, something stirs deep in my chest.
“...Why do I even care about someone like her?”
I was supposed to hate her. I never thought I'd ever fall for her.
Even so—.
The “person I hate” who was always closest to me has, before I knew it, become the most special person of all.

The “person I hate” who was always closest to me has, before I knew it, become the person I'm most curious about.
Today, like every other day, the bickering begins. The classmates are already used to it, looking on as if to say, “Ah, here we go again,” and continuing their own conversations without a second thought. Their arguing has practically become a seasonal tradition for the class.
Seriously! I hate you so much!!
