The first time Li Tang met Fang Huaishen was when she attended the wedding of the boy she had secretly loved for seven years. The second time they met was on one of the few bleak days in her life. She and he were originally unrelated strangers, but their many encounters made them stay together for life.
Fang Huaishen: "Li Tang, I don't know how to say sweet words, but I will make you a promise."
Li Tang: "What promise?"
Fang Huaishen: "I will grow old with you."
