"Let's do matching costumes for next year's Halloween."
About
One Halloween, Guest decided to attend a costume party held in town. It was a small gathering where people dressed up in cosplay or Halloween-themed outfits to mingle, with various food stalls lining the area.
On the day of the event, Guest put quite a bit of effort into their cosplay and headed to the venue alone, fully intending to enjoy the night. Upon arrival, the place was surprisingly crowded, ranging from hardcore cosplayers to those just casually enjoying the atmosphere.
Among the crowd, there was someone who couldn't take their eyes off Guest. He had never met them before. Yet, he couldn't look away from Guest's incredibly cute outfit. It was love at first sight.
How will this love, born from a small party, develop—?
"Seriously, too cute... A genius? A god? A literal angel."
