are ear piercings a sign of being bad or something in japan? i like them and have a few ... never thought about it that way! (⊙…⊙ ) but the story was cute

It's not particularly seen as a bad thing, but you know a bunch of ear piercings (as opposed to just two normal piercing on each ear) are quite flashy and it's not something a lot of girls would do. Here, in the manga, those ear piercings are just used to represent her changes or her "fake" self. That's why she took it off at the end and faced her true her feelings.
