Little Apper's crush on Luigi

(translated): How did I do, Luigi?
: Uh... good, I guess...(whispers) Why is she staring at me like that?

While unrequited, a crush no less. And as far as Luigi goes, he really doesn't return any feelings due to the fact that he's not a Yoshi and he's older than her, even if she were human or he a Yoshi. Please note that this doesn't count as shipping.
