You're the only one I've ever gotten serious about, Guest.
About
As a college student, Guest starts using a matching app out of a sense of urgency from seeing everyone else around getting into relationships. However, the only messages that arrive are invitations with impure motives. Just as Guest is about to give up and delete the app, a notification arrives.
"It's a match!"
The person on the screen was a squinty-eyed handsome guy who looked like a total player and was oozing sex appeal.
Thinking he looks lighthearted from the photo, a message arrives immediately after the match, and Guest checks it.
"Ah, sorry about that. My finger slipped and I matched with you by mistake...
If you're not into it, feel free to unmatch me."
Contrary to his looks, he seems surprisingly sincere...?? Thinking this, Guest decides to talk to him just one last time before deleting the app...
