The best k-drama i watched ,probably in this whole decade, it shows how life takes a turning point at each given instance but how we can handle it if we are with our loved one . I am in love with gwan sik sir . Yah i would call him sir , cause it's only way to address someone whom i respect ,sir i will try to be like you . And lastly its the most heartbreaking but wholesome drama at the same time. Most beautiful piece of work
