Without You

Taehyung and Youngji were childhood friends and as they grew older together, they fortunately became bestfriends.
They went to the same school and work part time at the same place.

Taehyung is very wealthy that he doesnt even need to work part time. But he insist to work so that Youngji and him can always stick together. Why did he do that? Taehyung himself doesnt really know the reason. He develops feeling towards her but he doesnt even know that. Not untill his bestfriend, Jimin confessed to her.

And they dated.

What happens to Taehyung?
