Namjoon finds a book on a small table next to the sofa in a living room. KIM TAE HYUNG is written in the cover of that book.

"It looks like a diary," he mumbles, as he turns to the next page,

and the next page,

and the next.

As he's turning the pages, he's starting to understand, the mind of that one peculiar member of BTS. The more answers he receives, the more questions pops up in his mind.

He actually does not know, what he thinks he knows. 

This is a story about the discovery of Kim Taehyung. What's inside his mind. His past. His insecurities. His worries. His happiness. The way he views the world. This is a story about the members and how they regret not trying to understand, how they're pissed because their Kim Taehyung is actually keeping a lot of things from them, and also how they realises that they never truly understand their second youngest member of the group.
