I came into this k-drama without any research about the topic or theme this drama will cover. It had a profiling setting what i like alot and there was no or slight romance between the main character and his wife who was killed. The message it had was amazing because thanks to this i rrflected on myself and started to think about my behavior toward others. I feel like i will think about this drama for a long time even after finishing and reviewing it.I did not get bored even for a minute and i felt excited about the whole plot and i was curious about the each episode.So i am ending this with a really good ratings as expected. Have a good day<3
