This drama for is so refreshing and nostalgic to watch and brought me to the past. It is a perfect blend if you want to laugh, sing, cry, and to be in love. The five friends shows different personalities that we could relate as a viewer. Seeing these characters that is somehow has the same personalities of our good friends and enjoys every special moments of our past. It is natural to look and to feel each characters and the situation that they are experiencing in the series. I love the scenes they eat together, have fun together at the karaoke (most people could relate to what they did in the karaoke house) and remember their days in the past. It gives me a perfect taste of each ingredients they put in this drama. I am learning to know the medical terms and know the situations of our doctors and nurses. As of now, we called them our FRONTLINERS as we continue to fight COVID 19. I am thankful to see this drama and I think 12 episodes is not enough for the viewers who really like this drama. I wish them more powers and keep safe.
