Under Seoul Skies

All the people started to walk away from the concert. Elisa and I started to walk out as well, when suddenly a male security ran up to us.

"Miss, you forgot your hat!" he said and gave it to me.
"Thank you" I replied and smiled at him.

Because of all the emotions I felt tonight, I completely forgot that Mingi took my hat and wore it almost during the whole concert.

For some reason he gave it to me upside down. I wanted to put it on my head when I suddenly see a small, folded piece of paper inside. 𝘞𝘩𝘢𝘵 𝘤𝘢𝘯 𝘵𝘩𝘪𝘴 𝘣𝘦?
"Jennifer, we need to go, otherwise we miss the bus." said Elisa impatiently.

I put the note quickly in my front pocket. 𝘓𝘦𝘵'𝘴 𝘰𝘱𝘦𝘯 𝘵𝘩𝘦 𝘯𝘰𝘵𝘦 𝘢𝘵 𝘩𝘰𝘮𝘦.

When I arrived home, I quickly took the note out of my pocket and unfold it. I see a Korean number. Whose number can this be from? I added the number on KakaoTalk, since Koreans do not use Whatsapp.

"Hello, who is this?" I typed.
I quickly get a notification back.

"Hi, thank you for borrowing your hat tonight. You found my note I see ;)"
