Identity. Relationships. Employment. Happiness. Friendship. These things are important to everyone. However, as we go through our lives, we come to realise that nothing is certain, and that everything changes, including the things we value the most. Two friends are reunited after one returns from abroad. Over the course of seven months, they meet several times, sharing their highs and lows, the difficulties they face, and their hopes and fears about Hong Kong. They meet at a different train station every time - and every time they meet, they find themselves at a different stage of their lives.
