Minatozaki Sana and Kim Taehyung were the perfect couple inside the whole campus of BYP University on their last year as senior high school students.

Not until Sana moved away and left everything in Korea. Including her sweetest first love.

Is there any chance that Sana will come back to Korea?

But will Taehyung give her another chance for their broken relationship?
