First of all, I definitely was not expecting this. I always use to drop this drama because of this plot( Person time traveled from past to present ). I love time travel dramas but i was just not that interested in this drama specifically.
Than after watching the whole drama, I literally didn't have words to describe the feeling i was having because the show is over now. This drama took me by surprise. It has comedy to make you laugh whole day, It has romance that you would love to watch again. Every episode is important in its own way. You never want to miss anything. The main leads are amazing. The chemistry between them is really good. It has those small happy moments that you don't see in many dramas. I can't spoil anything
I have watched many time travel dramas but this is definitely not less than them. Just go for it, Don't think about anything. You should watch this without hesitation. It won't waste your time.
