The first 10 to 15 eps were the best part of this drama where we see the characters going through different challenges in life somewhat realistic. Like the characters were actually shown studying before their exams and training before their sports meet. Their friendship also grew naturally while they hung out together and spent a lot of time together. The friendship aspect of this drama is very well written and well portrayed, whenever 1 person goes through difficult times, everyone would do their part to help him/her not just their romantic interest which was a new thing to witness.
The drama started to fall apart and become unrealistic when it became romance focused. It seemed like the characters were more mature in high school than in college. I loved Xiaoju in the beginning of this drama but when her crush for Cheng Lang lasted for 27 episodes, it became nnoying ngl. While Shiyi was always there for her, helped her and supported her in every possible way she still was stuck on Cheng Lang even after he started dating Lin You which was so upsetting. Their love triangle didn't work in any way for me. Also even after the time skip of 2 years she still felt uncomfortable around Lin You, like why??? Even after 2 years she still failed to recognize Shiyi's love for her. At first it was understandable that she couldn't see Shiyi in romantic sight as he was always fought with her, called her ugly, etc. But even when he changed his behaviour (carrying her bag, always saying encouragung words, always following her in her trips to support her) she still never saw him as mire than friend? Are you serious? Until the end it felt like only Shiyi was the one who actually loved her. They quarelled with each other throughout their life but 1 day when he said she doesn't dance well she suddenly became the most offended person in the entire world and also called him crazy for confessing. Ep 30 to 36 were so hard to watch. Shiyi was always the one who apologised first for even the smallest things and always approached her first whenever there was a misunderstanding. They were literally friends for 5 - 6 years but even the slightest misunderstanding would separate them. What was the point of having the friendship for so long if you can't communicate when needed. Shiyi definitely deserved a better girl than Xiaoju. Whenever he went to confess she always brought up her own feelings and didn't even give him soace to confess not to mention her change of behavior after Shiyi confessed. She was always mean to him and push him away and never talked after the misunderstandings even though Shiyi tried his best to sort them out. Shiyi literally chased her throughout the series but when it was her turn to chase him (after he went abroad) she just gave up without even confirming whether he was with someone or not.
I didn't get the point of Tao hiding her relationship with Bao from Xiaoju for so long. Also why did Shiyi visit so many spots in the name of proposing if he was going to do it in his friend's wedding?? Also it was a bummer that we didn't even get a glimpse of Xiaoju and Shiyi as couple after putting Shiyi through so many heartbreaks and suffering.

Overall this drama is great for you if you like the youth based and friendship focused dramas. Friendship was the only good thing in the drama. If you're looking for romance then you should probably find another drama.
