Wish

If you made an accidental wish, things may go wrong. Once in a blue moon, a shooting star passes through the night sky, the one that makes wishes come true. It lasts for only two weeks, but many inevitable events may happen during that span.

December 30, Joshua and Taehyung made a wish together. A wish that was supposed to be a simple joke. It just so happens that a shooting star passed by.

Waking up the next day, they've realized that what they have wished for came true. There was nothing they could do. There was no reversing this spell.

They had 14 days to act as one another without anyone suspecting.
