Don’t read this review if you don’t want spoilers.
I have to give credit to the writer for finding the best possible traits in a male lead in all history. Handsome king, just and loved by all, brave, excellent fighter, loves the FL unconditionally and provides her with constant support, praises, even provides for her poor choice of fashion, cooks for her in uniform etc. the list goes on. I would suspended my belief for all of it except an additional trait. He is a math genius with a sense of humor. That my friends is the most outlandish thing I have ever heard in my life ?.
The supportive hero called unbreakable sword is a very talented actor depicting two polar opposite personalities in a single frame.
Visuals are great, chemistry and acting is acceptable and even praise worthy.
Story line is a mess especially at the end. But suspend all belief and enjoy the ride.
