As OTP goes, they have hit the jackpot with this pairing. Both are good actors and their chemistry was great. The height difference is bonus for some viewers but at least it is not so exaggerated that the FL gets a crooked neck just trying to look the ML in the eyes. 

I'm particularly happy for the ML as he has been the "best man" in several dramas and now it is his turn to shine and show us what he can do in the lead role.

While on the whole, the show was good and enjoyable, it is not all sunshine and unicorns either. First of all, the show was slow in pacing. There was little doubt that the OTP were the chosen ones but there was a lot of push-pull and denial, mostly from the FL, and this went on for two third of the show. Several times during that long lead up to the confession, there were opportunities to just say the magic words and seal the deal but each time they (or individually) would push back and shout "we are only friends!" Even though they were practically confessing a minute ago. It slowed down the whole proceeding and extending the show by several episodes (probably by design). With no serious love triangles in sight and growing impatient from all involved, it was frustrating to watch and doesn't give us much rewards for hanging on.

The unicorns finally came out to play after the confession and you can almost feel the collective sigh of relief and everything just looks so much brighter and happier. Even subplots that threaten the leads sporting careers felt less threatening as we can see how supportive and loving the leads are to each other and you can really get behind them. I suppose one of the reason for the "go slow" in the early parts is that they were supposed to be elite athletes in figure skating and speed skating respectively. So some time and efforts were devoted to setting up that storyline and all the trials and tribulations that entails. The only problem is that both leads can skate but they are not even within shouting distance of an elite athlete. So lots of trickery were used to try to convince us otherwise. Cropping the shots strategically, a bit of CGI on doubles' faces, wide shots and moving rigs/platforms for action close-ups were used. Some were passable while others almost laughable. That plus the drawn out romance really made the first half a slow dance on ice.

With the focus largely on their developing romance, the sports aspect is given a more superficial treatment. Yes, lots of training scenes but they felt like b-rolls. There are lots of repetition but not a lot of details and tactics. Just do it, do more and try harder. It is even worse for the figure skating. A lot of the time the coach is just there to video the skating on his phone. Where is the choreography? Where is the review/critique/technical discussions? Just shouting "good/push harder" on the side line is not coaching. So if you are into figure skating or speed skating then this show will make you groan but otherwise, the sports are just backdrops and take up screen time between the romantic bits. It is ok but please don't look too closely.

There is a 2OTP and they are cute and sweet but they definitely played second fiddle to the leads.

In general, the writing is very text book youth drama. There are no shocking twists, there are ups and downs with their careers, friendships and love lives but every setbacks leads to breakthroughs. Old wounds will resurface but everything will be resolved in the end. Every dark cloud have a silver lining just about summed it up.

OST is nice and cheerful. You won't be humming anything afterwards but that's not the point. Rewatch is similar, it is a nice and easy watch but there are few highlights that will make you want to watch again and again.
