It feels a bit unfair how this drama is so underrated relative to its awesome quality, because this has EVERYTHING that a great drama should have:

1. Powerful and Meaningful Themes
This show revolves around finding your passion, facing and succeeding over obstacles, knowing and improving yourself, learning from one another, and friendship. Go may just be a "game", but we see the characters discover themselves a bit more through it and witness them grow for the better.

2. Character Development
Shi Guang, the main character, goes through a MASSIVE character development throughout the whole series. He isn't even bad in the first place, maybe immature at worst, so it makes the viewers root for him a lot. As mentioned by some side-characters, he is "like a sponge", and his willingness to learn from others and acknowledge his weaknesses significantly contributed to his improvements. Not only him, but we see other characters (actually, almost all of them) grow as well which is very satisfying.

3. Friendship
The amazing thing here is how fiendship is displayed in different ways: 13th High School Go Club friendship which is about mutual support, Yijianghu Go Club friendship which is about encouraging and strengthening each other, Fang Xu and Bai Chuan's friendship which is about making sure the other doesn't stray from the right path, Shi Guang and Yu Liang's friendship which is about rediscovering one's passion and setting an eternal goal to pursue, and of course Shi Guang and Chu Ying's friendship which is about finding a purpose to one's existence.

4. Acting
There is literally no blackhole in all of the characters despite most of them being young actors. Huge props especially to the lead actors: Juck Zhang who made Chu Ying impossible to hate but can also make you cry (I DARE you to watch episodes 32-34 without crying) and Hu Xianxu as Shi Guang who is undoubtedly THE STAR of the whole drama, one of the best actors of his generation to be quite honest. The young actor who played young Shi Guang also deserves a special mention as well.

5. Production Quality
The drama's timeline is from 1997-2006 so important details like clothing, appliances, places, even vehicles need special detail. There's definitely no weak point on that aspect. The cinematography and music are also very beautiful as well.

This drama may not be that famous internationally because there is no romance and doesn't ride the coattails of the ever-famous Hallyu wave, but you'll DEFINITELY miss out if you don't give this one a chance.
