I really like the chemistry between the lead characters. If you want romance I can fully recommend it. They built it up nicely and it feels very credible.
However, there are obvious misses and lazy screenwriting and it is really a shame. Some characters just disappear like they were never in the show and the last episodes are a bit too cringe to watch. The mother is just insanely annoying and I can't understand how no one can say anything.
But the story is fun to start with and only in Korea you can make it work between a chef, a rich business daughter and a gangster.
So, most of all, I really liked the couple and their acting, the show got me inspired and I enjoyed the bromance so that's why it got an 8.
