[url=]I'm looking for an old shoujo manga (before 2004), which has the main female character who has another personality. She was very shy and her other personality was very active. She loved a boy and sometimes her other personality came out and be a delinquent. It's a school life manga. Because at my country, it was publish under another name and suddenly ended, so I don't know where to find it 😢 [/url]http://4.bp.blogspot.com/-LMzTl8-kmj0/Ue9xohGjvYI/AAAAAAABz-4/K3FH-7p4h4s/s980/Tuoi-Hong-%28P1%29-08-009.jpg
