Chi-Lun, 27 years-old, loves trains. He is on the autistic spectrum. Studying maps and videos of transport systems in operation, he is well-versed in the transport routes of Taiwan. He, his sister and father are making plans for a train trip to Hualien after the easing of the pandemic. With a set destination in mind, he has to try to convince them. During the trip, his expressions are as fleeting as the view outside of the train window.
