I would literally travel back in time to a time called You.
It brings so many emotions to watch this drama, and even Kim Min Seok's OST made it even more emotional because I recognized his voice from Mr. Sunshine.; His Vocals is so magical.
The cast truly delivered, I'm so rooting for AHS; I need another chance to see him before this year runs out. And Jeon Yeo Been truly captured me when she was mostly Han Jun Hee. Her chemistry with the two actors was top-notch. I think I'll have to add her to my list of artists to watch.
Overall, A masterpiece of Casts, btw! Not really the plot.
