The next year, Su goes to Singapore and visits Chow's apartment. She calls Chow, who is working for a Singaporean newspaper, but she remains silent when Chow picks up. Later, Chow realises she has visited his apartment after seeing a lipstick-stained cigarette butt in his ashtray. While dining with a friend, Chow relays a story about how in older times, when a person had a secret that could not be shared, he would instead go atop a mountain, make a hollow in a tree, whisper the secret into that hollow and cover it with mud.
