Yoshifumi is Yui’s classmate. He holds affection for her, and continues his attempts to approach her, but she never gives him a chance. In the Cultural Research Club he’s often called out, and his pathetic side stands out more, but he also relaxes them with some of his casual statements.
When he was young, Aoki was in love with Nana, who moved away. She is said to have looked exactly like Yui.
