The story is very complicated but intriguing. I absolutely loved it but if you don't like shows that make you cry I wouldn't recommend since it had me bawling since the first episode .The chemistry between the leads is amazing. I loved how the you could definitely tell that it was a different person when the female lead traveled back in time. The acting was *chefs kiss. The OST for the drama is also amazing. One thing I will say tho at first I was really confused lol but like as the episodes went by I understood the storyline so if your watching the show and don’t understand it please don’t drop it cause you will get the storyline even if it takes a few episodes. Watch the show you won’t regret It ☺️
