I stumbled across this cover way back last year and found out that this song was in One Liter of Tears. I took the courage to read the book first, cried a river, and finally mustered up another ounce of courage to watch the drama yesterday, and I must say Junhoe's first verse at the beginning still gives me goosebumps because I cannot forget the scene where Asou Haruto read Aya's letter to him. The original song is great already, but it is this cover that really stands out for me. Junhoe and Jinhwan's voices match so well together, and full of emotions too. This cover really owns my heart
