Korean Drama " Must You Go? " is not very original but it is entertaining. Though it doesn't let the side characters shine and it focuses mainly on the main couple, the drama handles the fantasy-time travel element well and it doesn't get confusing. The past story, actually, was like a cinderella story taking place in Joseon era. The love story was also entertaining, heartbreaking, cute at times and it worked because the couple had chemistry. The love triangle was predictable though. The ending was also predictable and it had been used before and not just once.

Other than that, the performances were great, especially since the cast was mainly consisted of idol actors and actresses, some of them with few dramas under their belt. The soundtrack was nice too.

So, overall, six out of ten.
