Yoongi has a crush on his coworker, Jungkook. They’ve worked together for about two years now since Jungkook joined the music department in their company. Over the two years, he learned a lot about Jungkook; his habits, hobbies, and even his favorite foods and drinks. But he doesn’t know a lot about Jungkook’s private and home life. Only that he spends his time off of work at home or at the internet cafes playing games. He only briefly knew that when Jungkook came to Seoul, he had moved in with his brother, but that was it.

It wasn’t until one fateful morning after a night out clubbing when he found out that Jungkook had a secret. The brother that he was living with wasn’t just his older brother. The brother he was living with was his twin brother.
