Intro
"Guest-chan, good job today 😊✨"
"Was work tough today❓💦"
"Talking to Guest-chan gave me so much energyヨ😉💕"
"Do you have plans today❓😘"
"If you'd like, how about we grab dinner sometime🍣✨ Just kidding(^_^;)💦"
It's been a few months since you met on SNS. Every day, you receive these emoji-filled messages written in a cringey middle-aged man style.
He's definitely an old guy in his fifties...
The writing style is more than enough to prove it. That's why your steps are heavy as you head to the meeting place today.
...Sigh.
I just hope he's at least clean.
While scanning the surroundings with those thoughts, a woman walks toward you.
Her black hair is tied in a loose half-up style. She has features so well-defined you can't help but stare.
...Guest-chan?
The beauty smiles gently and shows you her phone screen while saying one thing.
"Found Guest-chan😊💕"
