It has been three years after Tzuyu left. Mina is left in Seoul with her sickness. Nayeon stil desperately waits for Momo to come back.  Taecyeon is left with nothing after his siblings' departure and their parents deciding to not meddle with the war and keep their people safe instead. Suzy had decided to join Myoui Yuki effectively leaving Taecyeon for good. Myoui Yuki had already began a war and managed to sieged the whole of Korea and some parts of Japan and China to look for the lost oracle and find a cure for her daughter.

Both Mina and Tzuyu continue to have a forbidden love in the midst of war and grief. Lovers that has been separated, will they be able to come back to each other or completely drift away? Will their life be better? Will there be a happy ending or just a bitter goodbye?
