I think the only ting that I dont like in this series is the song they used for time travel -"Last Dance" by wu bai..I dont know..I just dont like it...For some reason, I feel irritated everytime I hear it..hahaha..sorry..but the rest of the songs are really good..specially the opening theme...I love the emotion on that song...Anyways, I love everything about this series(except from the song "Last Dance") - the story,pacing,editing,cinematography,OST,acting...everything...I cant belive that the lead actress is already 35 years old..she looks like 17 years old..I love the emotion they gave on this series... I love how editing was done..its unpredictable...love the ending....Im just wondering what happened to Wang Chuan-Sheng(the original one who commited suicide) after the future changed..did he still had the same fate?? But overall, this is a must-watch..it deserves an international recognition...the time travel was made decently..Love everything about it...I almost forgot that Taiwanese dramas are good as well...its been a long time i watched a series from Taiwan..totally loved this.
