It was the end of sixth grade that he moved away, he left without a goodbye and ever since then i haven't touched that place again....

Lee Haeun and Kim Taehyung used to be best friends. They hung out in their treehouse almost everyday but then one day Taehyung moves away. Years have passed and they're both high schoolers now. Haeun's best friend is Min Yoongi and Kim Seokjin. What happens when the two cross paths again? Will they remember each other and start over their friendship or will they stay stangers?
