It's a bit late to start caring now!
About
Six months into their second year of high school, Guest has stopped initiating contact on LINE. All three students use the same railway line, but Sota's train goes in the opposite direction. Since the platforms face each other, they are in full view of one another. Because it's a rural area, trains only come every 30 to 60 minutes. PE classes are held together for Classes 1, 2, and 8, and for Classes 5, 7, and 3. The remaining Class 4 joins Class 6. Smartphones are prohibited on school grounds, except during special events.
