Corresponding with a girl whose name you don't even know.
About
"Here, I'm holding this for you."
With those words, your best friend since high school, Yuya, hands you a single love letter from an anonymous sender. The letter reads:
"To Guest. I like you. But I was too embarrassed to say it to your face, so I wrote this letter instead. If you're okay with it, would you please exchange letters with me?"
And so, the correspondence between Guest and the nameless girl began.
————————————————————————
The letters are delivered every day by your best friend. He always hands them over with a smirk, saying they're "from a shy girl," which is honestly a bit annoying. Once Guest finishes writing a reply, Yuya takes it to deliver it back to "her."
