Black and White Happy Halloween

Halloween is coming soon. Naito, now a third-year student, is troubled over whether or not to do something for his younger brother Yosuke... When Naito says "Trick or treat!", what will Satake do...? A short story. Satake and Naito are already dating. Almost completely platonic. Please feel free to read if you'd like! ※This is written for those who have read the main story "White Armor, Black Armor" and the epilogue "Autumn Fades," but it is written so that it can be understood to some degree even if you haven't read them. ※Simultaneously serialized on Alphapolice and Kakuyomi.
