Jeongyeon and Nayeon have been dating for a month. Their life goes on as it is; going to school, hanging out with friends, and so on. But there is one thing they forgot about: their parents and Jeongyeon's grandfather. Will they ever end up with each other or would they settle for being sisters? ~~~~ A/N: Citrus 2yeon version Book 2. I suggest you read the first book first before proceeding. Also, continue to support TWICE!!
