Tzuyu woke up to become a boy?! How did that happen?! Worst of all, "He" somehow convinced everyone that tzuyu went out for a vacation and that he's her younger sister! Will she able to avoid every TWICE member until He turns back into a girl?

There may be 8 members to avoid, but one only holds a grudge against "him" the most.

Minatozaki Sana.

Let the operation begin.
