Older female/younger male romance is my favourite trope and I enjoy watching the Olympics. This series was a delight! This series reminds me of Weightlifting Fairy Kim Bok-joo (another favourite series of mine) especially scenes about the slump period and the training

What I liked:
1) Acting - Wow, Wang An Yu gave a stellar performance as a soft-hearted student-athlete. He looked like an Olympian during his high jump scenes - the posture, running and jump. I enjoyed watching Wang An Yu's facial expression especially his eyes. Very expressive. The scene when Coach Luo Na was comforting him when he was wet was heartbreaking. Jin Chen was great at her role of coach and girlfriend too. Luo Na knew when to put on coach hat and girlfriend hat. I read comments commenting on Jin Chen's skinniness but I think that's how a (former) athlete who keeps good care of her body looks like. Chi Jia was also great as Coach Wu Ze.
2) Writing - I didn't read the novel so my comments will focus solely on the show. I love watching the journey of Du Yu Cheng throughout the series. From high school to university and professional athletics training. I also love that writers feature different types of track and field events from training to competition.
3) Luo Na characterisation - I love how the writers balance the different roles held by Luo Na - assistant coach, girlfriend, friend, daughter. As an assistant coach, she knew when to be confidant to her students. She also knew when to follow her instinct with the case of Zhang Hong Wen.
4) Duan Yu Cheng characterisation - I always giggled when watching his antics. Duan Yu Cheng is crybaby and playful, at times childish. I think he's needy/clingy with Luo Na because of his upbringing but he never showed signs of toxic masculinity.
5) Romance - wow, palpable chemistry between Wang An Yu and Jin Chen right from the start. Their kissing and intimate scenes were really hot.
6) Supporting casts - Wonderful supporting characters such as Coach Wu Ze, Xia, Jian Tian, Lian Shu, Jia Shi Li. Mao maoqi is my favourite because he is so endearing.
7) The reunion at the end - It's great to see Jia Shi Li in the last episode.

What I disliked:
1) A lot of the romance scenes were for the benefit of Duan Yu Cheng. I wish there was a scene or gesture that was done by Yu Cheng for Luo Na as his girlfriend not coach.
2) The English song that was played during competition between Duan Yu Cheng and Li Ge made me laugh because that was a love song but the scene called for rivalry!
3) I disliked Mrs Duan's action during Yu Cheng's decathlon competition. She shouldn't barge like that since it might disrupt his focus on the competition.

Favourite scene
The scene when Coach Luo Na was comforting him when he was wet. Heartbreaking. Wang An Yu's best performance in this series.
