I watched this because of Ren Allen and I saw some teasers on Youtube and thought his character seems refreshing and he looks hotter.
The idea of a childish or immature young man getting interested in being a firefighter to save people and start to be passionate about it is what I was expecting to see.

It was good when the focus was only about firefighters but then it started to focus on romance... which honestly speaking isn't all that interested and just plain cringey.

There was no chemistry between the Main couple, Ren tried his best but the FL was just.... too cold... not really a good actress.
It's sad because Ren looks like he really had fun filming this drama.
