I started watching this show bcoz of the story it has. I love fantasy. Hae Sung is the most adorable human I have ever seen. He is selfless and always thinking about his siblings. Jung won is the girl who loves him truly. Mr.Cha is the best friend of these two. But he has feelings for Jung Won from the day he met her. But she refuses him bcoz of her love for Hae Sung. After the tragic accident of Hae sung , his friends and siblings went through a lot. But he comes back to life after 12 years but no one knows how he came back to life. He was accused as a murderer and so he try's to clear his name by finding out who killed the student in school on that day. During this time, he find out that he don't have much time to be here, just like he came,he needs to go back too. I given 7 points for acting only bcoz of Hae Sung's acting. Others did it well too. But Jung won acting really needs improvement Music is perfect and I love the missing you OST I will rewatch it if I get some time Watch this show if u like fantasy
