To tell the truth, this drama is not for someone who doesn't like complex ones. This drama is worth the watch. It has been weeks since I have watched this drama but still, it's in my mind. I usually forget the dramas I watch after a day or so. This drama is about time travel and shows in this genre are usually confusing, towards the end you might understand the drama if you find it confusing. The setting, characters, and script make me feel somehow connected.I wish i could rewatch it again.
