That cafe (Namjoon fanfic)

I was sitting in my favourite cafe, a hot chocolate in my hand as I silently drank the remains of it, reading a book as the winter snowflakes set on the ground outside, wrapped in a scarf from the cold. Just another day in life, till I saw someone sit opposite me in the booth, he was wearing a black hoodie, his nose slightly pink, obviously from being outside.
"I love that book you're reading" he smiled, a cute dimple popping out...who is he?
