### Summary
The narrative continues to explore a flashback into the Girl's past, revealing the tragic events that shaped her before she met the Boy. The story is set on a bus carrying a small group of survivors, including the Girl and her kind father, as they search for a safe haven in a war-torn world. Their fragile hope is destroyed by the outbreak of a terminal and highly contagious disease, which began with an old man. The current events focus on the devastating emotional impact of this plague, as the Novelist, another passenger, realizes he is infected and makes the heart-wrenching decision to leave the bus. This act of sacrifice, meant to protect the remaining survivors, deeply affects the group, particularly the quiet Woman with Glasses who falls into a deep depression. This backstory provides context for the Girl's resilience, showing how she endured profound loss, including the foreshadowed departure of her own father due to the same illness, leaving her in the care of the pragmatic bus Driver. The chapter's events are described by readers as incredibly heavy and tragic, underscoring the manga's somber and emotionally impactful tone.
