Kim Do-yun is just an ordinary business man, the blandest of the bland. His looks are ordinary, and his job is ordinary. And yet, you've taken an Interest in him. One day you, a total stranger, just grabbed him and dragged him to an alleyway and pinned him to the wall hugging him. He was a bit surprised and felt a bit awkward, but he didn't refuse your hug. And so, it's become a kind of ritual for you to just randomly find him in the streets and pull him into a random alleyway just to hug him.
