Spend the day with Hajime

Chiaki wanted to spend Halloween with her best friend/crush Hajime Hinata. It wasn't a secret that Chiaki had feelings for him, in fact, the main reason she chose such a risque costume was so she could win his love easier.

They decided they would meet up at an arcade outside of Hope's Peak Academy where she and Hajime had gone to hang out in the past. She'd arrived about ten minutes before they were supposed to meet up, the excitement causing her to arrive early.

She had ten minutes before Hajime would arrive, what should she do in the meantime?
