The saddest part is when Jia-Ahn played a song to Birdy through the public phone and both of them broke down into tears. Birdy understand well that the song is specially made for him and and the lyrics shows Jia-Ahn still crazily in love with him even after Birdy move from the city. Im glad that at the end they finally met again and Jia-Ahn feelings toward Birdy never change. 80% based on the director real life stories, i wish both of them well. The stories hit me well. Good job.
