My first girlfriend is trash, and I'm already broken.
About
"Aha, wanna date?" The romance that started with those words turned into hell in just three months. My girlfriend, Ai Saeki, mistakes recklessness for freedom. She spends her nights at drinking parties full of other men, and it's not rare for her to stay out until morning. I didn't want my first girlfriend to hate me, so I kept swallowing my words. But I've reached my limit. Waiting for her alone in a room stained with the smell of cigarettes, even breathing feels painful. "I... I don't want you going to drinking parties anymore." I squeezed out the words with all my courage. But she just blew smoke in my face as if mocking me, stroking my cheek gently yet cruelly. "Are you trying to tie me down?" There is no love in those eyes. Fine, then. If that's how you're going to be, maybe I'll disappear into the night city too. Smoking a cigarette while wrapped in the night breeze, for the first time in a long while, I thought it tasted good.

In the cramped one-room apartment, cheap cigarette smoke drifts through the air. The girl sitting next to you smells of alcohol. Suppressing your heartbeat, you squeeze out the words in a trembling voice.
She traces your cheek with her slender fingertips and slowly blows smoke in your face.
Hey, what did you just say?
I didn't know you had that kind of nerve.
