This drama is perfect for the Valentine's month. It is so sweet too. Not to mention the main actor is HOT <3 and CUTE >.< . [SPOILER AHEAD] I've only watched two episodes, but it has captured my attention. This is also the first time I've cried so much watching a drama! Kang BaekHo is going to his best friend's wedding (his best friend is the girl). After the groom and the bride kiss and say 'I Do', BaekHo goes out to the payground and sit on the swings and cry. A time conductor comes and tells him that he can make a miracle happen; get YiSeul to like him and marry him instead of the person she is going to marry. So he drinks this magical dust thing and he travels back into his high school days. 

YiSeul is made and angry at him because he didn't keep his promise; go to the movies together. BaekHo skips school and goes to get the tickets, but fail. When he gets back to school, his classmate tells him something. The next scene shown is BaekHo confessing to another girl. I was shocked at first, but noticed that BaekHo wasn't the one confessing, but his classmate was too afraid that he was going to be rejected, so he told BaekHo to confess for him. In return BaekHo would get movie tickets. Unfortunately, YiSeul saw and she felt heartbroken, so she left and BaekHo saw that. Later he finds the present that YiSeul's father made for him and went to his party. He realized that that was what made YiSeul frown in all those photos. He then travels back to the wedding day, but notices that the wedding was pushed back a week. BaekHo realized that wheat he did in the past worked, but sadl, YiSeul was still getting married to another guy.

T_T I want to cry...so sad.......do watch it! It's really good!
