at the beginning of the drama, the whole time travelling really intrigues me. I was so curious what's going to happen, how is he gonna change his future and all that. but as time goes by, I was still curious, but I fall in love with the couple so muchh. like soo soo muchh. sometimes they're cringe but they are so cuteeeee i just kept watching. I fall in love with both characters, their character development, their love story, their feelings and all that. The next thing I know, I don't care what will happen anymore, I was just desperately hoping that this couple will have a happy ending and live happily day by day. It's been a while since I'm this emotionally invested with a couple, I cried when they fight and cried again when they made up, and happy when they're happy. And thats why, I give such a high rating. and plus, acting. amazing of course as expected from shin min a and lee je hoon. but in terms of the storyline, it was good until the antagonist came in the picture. It was kinda weak (?) maybe I expected more, idk. but as i said, the storyline isn't what I'm interested anymore at that time. so joon and ma rin is all I care.
