I think I recognized the voice who sings the soundtrack at minute 56. (The umbrella scene). The singer and also the song is similar to one of the OST in Hometown Chachacha; Wish by Choi Yu Ree.
Just finished and glad that I decided to watch it. It’s beautiful and hurt deeply. It makes me ask myself ‘what if’ a million times. What if we could do things differently. It is a sad drama, but definitely worth watching and reflecting upon.
It’s kind of funny for me because currently I’m watching two dramas at the same time. This drama and ‘Hi Bye Mama’. In ‘Hi Bye Mama’, Kim Tae Hee (Rain’s wife) plays as the ghost. Both husband and wife are good at playing as ghosts 😁
