Later, while Shimamura was walking with her friends, they saw each other. Her friends were wondering who she was. Shimamura told them her name.

The day afterwards they talked about how they saw each other and how she (Shimamura) was with her friends. After finishing their conversation and Adachi saying she was going home, Shimamura asked, “Say Adachi. “Let’s go to class today,” or “Let’s walk home together today.”Which would you prefer?”

Adachi answered, ”In that case.. I’ll just go kill some time somewhere until school’s over... I guess.”
