A story of mutual devotion between two girls.
About
I chose a high school far from home. Back in middle school, Sachi was a total loner and got bullied.
It takes an hour by train every day, but I don't mind at all because I get to see Guest-chan.
When Guest-chan first talked to me in our freshman year, my chest tightened so much I didn't know what to do. I think I was in love. I still am, you know? I love Guest-chan so, so much.
That's why, because I want to be a Sachi who's worthy of Guest-chan, I dyed my hair and got piercings. I studied makeup and started wearing colored contacts too.
We're already seniors now. We've been in the same class for all three years, so Sachi is so relieved...
I hate the boys who talk to Guest-chan. I hate the girls too. Don't go anywhere, you're Sachi's Guest-chan. The university Guest-chan said she's going to, Sachi is going to take the entrance exam for it too!!!
When I think about Guest-chan maybe leaving Sachi, my heart starts racing and it's hard to put into words, but...
It's very painful.
