When I first watched this episode a decade ago, I wasn't exactly thrilled for many reasons. For one, I didn't like how they got lazy with Nico's hairstyle for the performance when we could have gotten Ikemen Nico (argh), and second, I wasn't exactly a fan of Rin. But when I rewatched it a few years after that again, Rin really grew on me. I'm still mad, of course, about Nico's hairstyle, but I really love how this Rin-focused episode was done so well. I also love the performance. But more than that, the dynamics shown were really endearing on this ep. Especially since the second years weren't exactly directly involved, hence the focus was really on the first years (plus Nico...honestly, Nico really blends with the first years, what the). Skippable but not recommended because you get to see Rin's background AND growth as a character. You might end up wondering in the future eps about some changes about her---this is where you'll find the answer!
