The promise of this show is not new but it was executed well. Acting was good and the story engaging. The interesting thing about the plot is that the love line is integral to the story but it doesn't drive it. It is the decade old friendship and e-sport world that forms the core of this drama. Because of that, the romance was fairly straightforward. There was a little bit of angst but no more than a few bumps. However, I don't quite understand why they introduce the senior as a competitor for the ML as it was quite obvious from the start (that is why I don't consider this as a spoiler) that he doesn't stand a chance with the FL. If anything, the writer took it too far and he would have been better served if he just come to his senses and bow out gracefully. What we ended up with a sad and broken man for little gain to the drama.
What is also interesting is the patriotic angle. Thankfully, it is not too jingoistic (except towards the end) and some may argue that it is more about making dreams come true for the younger generation. Whichever way you want to see it, it is not a hard sell and the drama is light and warm-hearted in most parts.
Back to the romance, there are several romantic plots in play, some front and centre and some were hinted at and stayed unanswered in the end. It was nice that there was not a lot of angst with the love lines and what there were was resolved fairly timely so that the OTP (and others) can spend more time being lovey-dovey and cute. Speaking of cute, the FL really knows how to do aegyo. Other FL can learn a thing or two from her. These romance sub plots were used well to space out the tense e-sport dramas and friendship angst and some of the funniest moments are generated by the interactions of the OTP.
