Shuka Saito -- PaPaPa（パパパ）

Didn't catch this anime "Ore wo Suki nano wa Omae dake ka yo"（俺を好きなのはお前だけかよ...Are You Really the Only One Who Likes Me?）when it came out for the Fall 2019 season. Then again, since my anime buddy has declared that nothing good has recently come from light novels in the last decade, it's not a surprise that he didn't select this one for viewing. From what I've read of the synopsis at Wikipedia, it sounds like the story of a love polygon filled with (initially, at least according to TV Tropes, unlikeable) high school students, and it's certainly got a few names in the seiyuu industry that I recognize such as Haruka Tomatsu（戸松遥）, Nao Toyama（東山奈央）and Yuuma Uchida（内田雄馬）.

One of the seiyuu in the cast is Shuka Saito（斉藤朱夏）and she's also the one behind the very upbeat opening theme "PaPaPa". Written and composed by Kei Hayashi（ハヤシケイ）, the reason that I put this on the bookmark list is that I am such a sucker for happy horns in a J-Pop song and there is something slightly Shibuya-kei-esque about the arrangement. This was released as Saito's debut single in November 2019 and it reached No. 12 on Oricon.

I gotta say here that despite hearing all of the parodic riffs from two seasons' worth of "Kaguya-sama: Love is War"（かぐや様は告らせたい〜天才たちの恋愛頭脳戦〜）soundtrack, I was still surprised to come across this take on one of the most famous themes from "Star Wars" being used to describe a bench.
