Sunohara Inn[]
Aki Shina[]
Nana and Aki.
Nana immediately took a liking to Aki upon meeting him. Endeared by his timid personality and entertained by his short stature and "cute" appearance, she spends the majority of her time at the Inn hanging out with him. She is known for sleeping in his bed without his knowledge. Like Ayaka, she is very clingy and sometimes possessive of Aki.
After learning that Aki had never played video games before, Nana makes a habit of teaching him how to play, often having him sit on her lap while doing so. She eventually starts bringing Aki on hangouts with her friends, and becomes visibly jealous and upset when they begin to flirt with him. During the fireworks festival, Nana held Aki's hand for the majority of the event.
When having to leave the Inn at the end of summer, Nana makes Aki promise her that he'll get better at video games for next summer. However, she returns to the Inn the following week and announces that she'll be visiting more often, with Aki most likely being the reason why
