There's a lot of enjoyable aspects of this drama but # 1 reason is always:

1. Zhai Zi Lu - ML. He is phenomenal. In the drama wasteland amongst pretty faces famous w/o much acting skills, Zhai Zi Lu is not one of them. I first enjoyed him as the sleezy boy in the Pavillion as a small supporting role then found him as the ML in Hello Debate Opponent S2 followed by Calorie Boy. He will be the reason you'll want to watch any drama. I love his expressions (go full force on ugly cry scene and not worry about how great he looks like some idols....). His voice is never dubbed which I think it should be a part of any actor's skillset (unless they really have a heavy accent that warrants it).

2. ML FL polar opposite personalities. They are not my favorite pairing in terms of chemistry but it's nice seeing a race car driver falling for a brainy girl. They complement each other and somehow it works.

3. Race car stories not so common. I mean how many office dramas have you seen vs race cars?

What I didn't like:
Zero to little character developments on supporting roles and there were a lot of potential too.
Draggy after abrupt break up trope ~ ep 16. Felt forced to prolong the series into a different direction making you pretty much want to 2x watch it through.
Patriotism -- hmmm is that due to censorship? suspicious....
