I already asked on reddit but got no response, so I'm hoping you guys can answer. I've had this song stuck in my head for ages but no matter what I search I can't find it. It's a song sung by Rin (with Len dancing) - the PV is a cute black and white sketch animation where Rin is a schoolgirl trying to impress the random guy she likes (she describes brushing her teeth and taking vitamins) but all she gets is a pat on the head from this guy and it frustrates her. The chorus shows her telling him off, holding several cue cards that get messier and messier (she repeats the same phrases a lot during the chorus). And during the instrumental Len is dancing, dressed in a high school boy's outfit. I think the title of the song has a capital 'A' in it, like 'Get-A' or something odd like that? But I've searched that and nothing has come up.

Any help or links would be appreciated, I used to love that song and I really want to find it again, it's been years since I last heard it.
