I don't even know if I can describe everything I loved and hated this drama in words cause there's so much. But this is most definitely one of the best time travel dramas I have ever watched and best school drama this year. First of all the actors and actresses are AMAZING. Each and everyone one of them fits their roles perfectly. The storyline is so unique and I think a part of why I loved it so much was because of how heart warming the drama was. Not only did it focus on romance or friendship, but it also focused on family as well. It had a little bit of everything. I loved the character development especially in chen junhe and li jin bu's characters. The fact that chen junhe gave up an opportunity to take care of jingtong and the baby that wasn't even his and marrying her so the child din't have to grow up without a dad. As for li jinbu, her going back to going through everything with her mother helped her character mature so much because she was always blaming her mother but after, she realizes how much her mother went through and started to appreciate everything. Also overtime, you could see the maturity in li jingtong grow especially when she got into the relationship with wu zhi xun and the death of her father:(( The only complaint I have of this drama would be wu zhi xun. I know the drama is trying to portray the reality of some situations but I don't like how they didn't mention him or let us see him in the future. He's probably like 40 something? and still doesn't know he has a kid walking on the face of this earth. The adult actors and actresses were AMAZINGG. Like they fit the adult characters of the younger ones so well. Even the facial expressions and the way they act really seemed as if they grew up yk? ALSO I would have liked more scenes of jin bu and duan xiao once she returns to her normal life because it was kind of like an open ending? I honestly loved the drama otherwise. 10000/10:)
