Here's one thing I know for certain: if I never see you again, the world will end.
Water Moon meets Before the Coffee Gets Cold in this cosy YA fantasy set in Seoul about a girl who must restore the timeline while trying not to fall for a handsome rogue time traveller.
Yang Mina has spent her life training for the Descendants, a secret organisation who protect the timeline.
But since moving to Seoul, everything is falling apart; the Descendants are corrupt, her sister has been erased and she can't pass Calculus.
With her very existence on the line, Mina teams up with Yejun, a cute illegal agent, to restore the timeline and her sister. But between time travel dates filled with cheesecake, teddy bears and butterflies, Mina grows closer not only to Yejun . . . but to discovering the truth.
