I still love Ichiki she played dirty but if she did nothing she would just be that character who is pitied on not getting a chance with Futaro ichiki is still best girl for me
This is my take on this manga but the reason why miyamura got ear pircing was because of him being bullied and left out. He figured if he could tolerate the pain of getting ear piercings he could also tolerate the pain of being alone well at least that waht i think
