haha, rush to where exactly ? sue the the suicide-faking girl and get back her career ? they could've just done it with 2 eps. THE END. The goal is important, but it's always about the journey. This type of drama is always about the journey.
what happened at the very end ? after they bury the box. the ML holding the spell book ? what does that even mean ? he was the one that buried it 300 years ago ? or that is in the future ?
