To begin with, this drama has an unique concept, re- entrolled students. Let me promise you, this is not your typical high school drama with usual love triangles or leads chasing eachother or childhood sweethearts. This drama is quite different and portraits about the real student crisis and how they deals with it. They are scorned by their peers and even teachers because they're repeaters.
The main leads are Fang xue and Wei lei. I really liked their chemistry. Their subtle romance is endearing.They are very comfortable with eachother. This drama focused on each student and not just the main leads.The story of all students are perfectly blended together without poisoning the whole atmosphere. You can feel their friendship and you may feel like you are one among them.
Since, they are repeaters they had more pressures than a regular student. But, they got the best class teacher who supported them endlessly.

SPOILER ALERT!!!
Now talking about the main leads, they have a different bond. The romance here is mild but is strong enough.I love how much wei lei has changed for his fang xue. One of my favourite moment is when he was not ready to sing for her in ep13 v/s how he himself danced and sang for her later in ep22 . He did that only for her, even though it was quite embarrassing for him. We can see how their relationship grows. It is slow, but kinda cute.
I have to say, everything about this drama is top notch. Much much much better and more realistic than any other high school dramas.( I found it similar to 'when we were young' . Both are highschool dramas and realistic ones.) Right from the intro to the very end of this drama is stellar and well made. The intro is really creative. Also, there is a small interview at the very end of each episodes. They are either real students or characters in this drama.

SPOILER SPOILER SPOILER!!!
Ending is an open ending. I had a hunch it would end somewhat like that. Just because this drama is so real, a slice of life!! Even though i'm not a fan of these type of ending, in this case i think i can understand them. I understand why they decided to separate. A long 10 years had passed. But, their love towards eachother remained the same. They seperated not because they don't love eachother. They really love and care eachother. That's why when fang xue suggested to separate, wei lei agreed. Not because he don't love her, but because he loves her and respects her decision. He believes whatever she decides is the best and good for both of them. Even at the end wei lei assured that he loves her, no matter where.
Moreover it's an open ending not a sad ending. There is hope, a hope that they will meet again. Because ,a separation is a new beginning. They both hopes that they will meet again for their NEW BEGINNING!!

FUTURE VIEWERS TRUST ME, THIS IS WORTH WATCHING.
