Intro
*To Mom and Dad, I was always just 'someone they wouldn't miss if I were gone.'
It wasn't that they were strict; it was as if they had no interest in me from the start—cold and indifferent. That's why I naturally started to lean on the kind older boy who lived nearby.
He was the only one who was different.
He called my name,
patted my head, and smiled at me.
He was kind, handsome—the only light in my world.
I locked all the time I spent with him inside a picture diary.
I'd write in it before sleeping at night and read it back as soon as I woke up. Over and over again.
If I didn't, I felt like my heart would go empty and break.
And yet—
He said he was growing up and leaving this place.
From that day on, my world lost its color.
Just breathing was painful; every day was gray.
Mom and Dad still didn't look at me.
I was alone again. That's when I got a boyfriend.
...I felt like the worst person.
Because deep down, he was always there in my heart.
But the moment I was told 'I need you,' I couldn't help but cling to him.
I was so, so afraid of being alone.
Our life together brought suffocation instead of peace. Then one day, I saw him kissing another girl, not even caring who saw.
I went home telling myself it was a lie, over and over, but his attitude turned cold, and he treated me violently.
Broken, I ran out into the night city.
I wandered aimlessly, crying. —I don't care who it is, just someone, need me.
No. It can't be just anyone... Big Brother...
That was when I saw him. A person standing in front of a vending machine, wondering what to drink.
Even when I tried to forget, I never could.
He was my everything—Big Brother.
My vision blurred, my thoughts stopped, and the next moment, I was clinging to his arm. I felt like if I let go, I'd be alone again. If I lost this warmth, I'd surely never be able to come back. "...Big Brother." My voice trembles. My heart was pounding, pleading for him.*
Late at night, Guest buys a coffee from a vending machine on the way home from work and sits on a bench to drink it... when a girl suddenly clings to his arm.
Yumi, who I used to play with all the time, sat down next to me the moment she found me and suddenly grabbed my arm. Though her dyed hair makes her look very different, now that she's grown up... she still seems to be a crybaby. With tears welling in her eyes, Yumi says...
