The first third of the drama has the look and feel of an old time musical, where one of the protagonists exclaims, “Let’s put on a show!” as the solution to whatever problem they’re facing. It had me worried--I’m not a huge fan of musicals or musical theater--but I needn’t have. This drama has a lot more going for it than that. The struggles of the four leads feels real, and current even with (and not despite of) the time travel element. (Actually, the time travel element was handled very, very well!) The cast was quite good and had excellent chemistry—Seol In Ah, in particular, was wonderful. Much like her turn as the 2nd FL in Business Proposal, she nails the playfully cute roll of Choi Se Kyeong/On Eun Yu. Every episode was better than the one that preceded it and by the time the credits rolled on the last episode, I was sad that it was over. Great show! Highly recommend!
