Hi everyone I'm Vietnamese and I really like Alex To's music. I used to watched Engagement for love 2006 (Taiwan - Hongkong), and ost is so so good to me but I can't find name of song by Alex, it's not a song by Ambrose Hsu too :(((( It's a song with 2 letters in name Please let me know if you know about that song, thank you by my heart ❤❤❤❤❤ I'm no good at English so I'm really sorry if I have some mistakes T____T
