Plot Summary

Graduate student Yi-wen gets on the wrong train and meets a former classmate from her past, Wei-chiang, who is now a university lecturer. The two alight together at the same station when they both find themselves having boarded the metro headed for the wrong direction. The two end up going to dinner and bumble about in awkward, fair-weather catching up when they both realise something about themselves that they have never openly admitted over the years.
