Help me find this manga please

This is a shoujo manga about a delinquent female lead and male lead. If I remember correctly they met for the first time in their first year of high school or middle school. The male lead was looking for the female lead cause he heard she was really strong so he wanted to challenge her but he only heard her name and didn’t know she was a girl. Stuff happens and they become very good friends. The ML falls in love with FL but she doesn’t notice. In one chapter, the FL skips school to attend her siblings parent conference I think cause they have absent parents. I also remember one chapter where she meets a rich young lady and helps her as she was being harassed, they switch uniforms for the day, the ML was really flustered when he saw her all lady like. I really want to find it again, thanks
