Rate- 10/10. This is definitely one of my favorite drama. Who can resist Yoo Seung Ho though? ;) The chemistry between the lead is amazing. I might say this a lot but you might need to prepare tissues for this drama too xD maybe I'm a crybaby but seriously, I cry a lot while watching this. The loyalty of crown prince's bodyguard is to die for. It was amazing. And Hwa Gun's character? It's impossible to hate her :') L's acting here is good
