The first day Lun (Chou) enters Tamkang Secondary School, he meets Yu (Kwai Lun-Mei) in the music room when she is playing a mysterious piano solo. The two become intimate friends and spend a lot of time together. He often asks her "What's the melody you played the first day we met?" but Yu unfailingly replies: "That's my secret." One day, Lun asks Yu to meet him in the music room but Yu never showed up. Lun cannot find her. Later, Lun sees Yu in an old photograph and what surprises him is that Yu is standing next to his father, Chiu (Anthony Wong) in the photo!

Hmm,wonder if this show is nice?
