He failed, we still make fun of her for her cute stupidity.
In an appriciative manner, anyway.

She wasn't stupid, Tomo was the stupid one (and too confidant to realize it, like an idiot). Ayumu is a nefelibata or "cloud walker," she day dreamed and just lived in her head. Its why I connected with her, cause I was the same in school before I was an adult (I even earned a nickname too). In fact she knew she was "spacey." She tried to reinvent herself when moved from Osaka, but Yukari and Tomo (mirrors of each other) blew "Osaka's" chance.
Now watch this clip of her being adorable and if you called her stupid, I'll tell Yukari you owe her money!!
