Too Young (1999)

Mo Tzu Yi is a high school student who likes to hypnotise himself by listening to tapes, intending to explore the world beyond. Chen Wen Yi, a student who failed in class before, cares about nobody and nobody cares about him. Tzu Yi begins to shift his attention to Wen Yi. Rumours abound about Wen Yi—he had once committed suicide. As two chords with the same frequency achieve resonance when played together, Tzu Yi and Wen Yi begin an interesting journey together.
