An Estimate of the Distance Between Two People (Part 5 of the Ice Fruit Series)

Spring has arrived, Houtaro and others have entered the second year of high school. At the same time, the "Ancient Book Research Club" where they are located also welcomes a new student who joins temporarily-Ohinata Tomoko. Ohinata Tomoko quickly became familiar with Chitanda Eru and the others, but one day, she left an incomprehensible word and told them that she would not join the club. The reason seemed to be the conversation between her and Chitanda in the activity room, but Houtarou disagreed. With her character, it is impossible for her to harm others. During the marathon race held on the day of the deadline for joining the company, Houtarou speculated on the truth behind Ohinata's change of heart while running!
