This show is the goat of all dramas, so you should definitely watch it! I mean, the plot is about an 18-year-old guitarist who goes back to 1995 after fighting with his father and the first person he meets, guess what? Yes, it's his father, but the same age as him. I won't dwell on the events that take place, 'cause it's best to discover them by watching, although some of them may be predictable, they're still quite enjoyable. Also the soundtrack is amazing, so you can look forward to it! The actors and actresses did a wonderful job, so much so that I fell in love with On Eun Yu (Seol In Ah) and I wish she was real lmao.

Hope you like it <3 <3
