OMG- Thanks a lot, that's the one I've searched!!
A long time ago (circa 10-15 years) I have begun to read these serie, but never finished it. That's why I'm searching for it, though I don't remember the content clearly. Whatever, here comes the summary (as far as i could remember):
● the MC was a blond girl at High School (I'm pretty sure that she was the 2. year.)
●she was bullied by female classmates (I believe that it were two girls)
● she was shy and has had problems to defend herself
●she was scared that somebody might find out her secret hobby
●her hobby was to cosplay as gothic lolita
●she developed a second personality, which were bolder and fought against her bullies
● the name has had 4 letters also the name of her second personality
●she met frequently a boy from her new class by coincidence and as a result they started to get involved with each other
●after school she spended her time on the Jingu/Harajuku bridge with cosplaying
That's not very much, but all I recollect so far. I'm grateful for any suggestion. (●'◡'●)ﾉ
