I'm at ep 11 and expressionless ML is getting boring sometimes but he is really sweet to FL that I often think…
Logically u r right.... But since it's dramaland & our brain supposed to be on rest so here is what i think.... Ever since, Yu Da lost to Lan, he came to realize that almost every GO player in china is better than him..let alone a champion... He wanted to learn from Lan but after he learnt Xi he is better than her, he asked him to teach but Xi He suggested to go for champion that's our ML. Searching internet for champion & chasing him is far more difficult approach. He thought to learn from whom he can approach easily.
Female lead was most clever, lovable & loyal character among all throughout the series...Male lead as usual martial arts expert always protect her... Together with second lead pair, they were an awesome team... Some reviews may be misleading so don't miss such a great show.... I was almost going to drop it reading some comments but after 5th ep., i couldn't... & i m glad i didn't drop it.... Highly recommended...
