I didn’t know that it will turn out like this? What will I do now? It will be really awkward between us. I don’t know what to do?

Tiffany, Seohyun and Taeyeon were the best of friends. They were not the most popular girls in school but they did not care about what others think. In school, they were laughed at sometimes for being nerdy and all but they didn't care. They had one another and nothing else mattered. However, that was before one of them changed and everything changed.
