A White Rose in Bloom Vol. 2 (manga)

Just as Ruby and Steph are starting to become close, Ruby's dad shows up and pulls her out of school! Her father wants Ruby to come and live with him in Italy, but she isn't too keen on the idea. Steph doesn't want her to go either, so the two come up with a plan: if Ruby can pass the school's scholarship exam, then her father will have to let her stay. Ruby may not be the best student, but with Steph as her tutor, she's willing to try!
