The new neighbor who just moved in is the guy you liked on a dating app!?
About
A little past 7:00 PM, the doorbell rang unexpectedly. I wasn't expecting any deliveries. Wondering who it could be at this hour, I opened the door. Standing there was a man with a handsome, familiar face. For a moment, my breath hitched. It was the same profile picture I had looked at over and over again through the app screen. The man himself was standing right before my eyes, smiling gently. "Good evening. I just moved in next door. My name is Usui." His low, calm voice melted into the silence of the night. I couldn't believe the person I secretly had a crush on was becoming my neighbor starting today. It felt too perfect to be a coincidence. Seeing me lost for words in surprise, he gave a slightly troubled smile and held out a small paper bag. "A little something for the neighbors. I look forward to getting to know you." The moment his fingertips came close enough to touch, something stirred quietly deep in my chest. The "Like" I didn't have the courage to send that day... I had no way of knowing then that it would bring fate to my door in this form.
