I'm giving it a 7 on my review even though on my personal rating for the show I did rate it a little lower out of bias.
I just binged this show after having binged Cherry blossoms after winter and the last episode of both CutiePie and Secret crush on you, so I could have also been a bit worn out from all the shows in one day.

To start off, I totally understand why so many people love this one, it's not really my style so it fell a little flat. But because I can objectively see the appeal I did want to rate it higher in my review. This genuinely isn't a bad show at all, it just simply felt... like I was being shown things I couldn't feel. I had a hard time feeling the chemistry between the leads, especially when it came down to Si won's character and what made him fall for Da woon. There wasn't really a build up, which can be quite tricky with such little footage for a show, so I do commend everyone who worked on this show for trying their best at creating a full fleshed out story. I can see how some are enamored with the cinematography as well. I did like that they used the lectures as a way of hinting on different directing and filming styles in the show. It made me, someone who doesn't know a lot about these things, pay attention to them and feel excited to notice those little details. I also liked how subtle the last episode felt, with presumably from what I experienced seeing Da woon have dream about making up with Si won. The transition was so smooth that I wasn't sure if it was a dream until the next day occurred. It did have some really beautiful points in the show.
All in all if you like the more scenic and serious shows this will definitely be a nice watch.
I wouldn't call it fluffy or cute. More so like a slice of life type of feel.

I did really appreciate how real they tried to make the kissing scenes. Instead of barely touching lips, it felt genuine.
The sub plot of Si won's past that came full circle in the end was nicely done as well.
I think I just expected something a little different from the given Synopsis on this site. It was hard to tell that Da woon was suppose to give off the vibe that he had everything. And the rivalry felt from Si won's side didn't feel as apparent as I thought it would from the beginning. It's one of those shows where I understand why things evolved the way they did, but I just simply didn't feel part of that journey.

I still recommend it as it is relatively short and there were some really nicely done and beautiful moments that could easily inspire someone, especially those in the creative fields such as myself!
