A truly beautiful story where love is timeless. No matter how much both try to forget each other through time travel or to save one another, they will end up falling in love because that's what their fate or destiny is. Byeon woo seok, I dont know where he has been all this time, but he is such an outstanding actor. It was really a comfort drama which made me go through an literal emotional rollercoaster every monday and tuesday. Indeed it was a bit frustating and exhausting to see them time traveling several times and thereafter situations getting complicated, but that's what made the last episode more satisfying and thrilling. As much as it made me cry, it also made me laugh hilariously because of their comedy. A true love story indeed!
