Very easy to watch drama, as the episodes are short and crisp, and the cast are excellent, especially the male lead, Zhao Yi Qin ( watch out for him in other shows). The supporting actresses are also cute and likable. Main actress overacts a little, and I don't like the character ( sometimes too stupid to believe ). Each phase of their youth are captured well, and not draggy. They go through 3 years of high school a 2 years of Uni within 12 episodes. Total of 24 episodes, so will end next week. Will review if ending is worthwhile.
