I love Haruta Nana's work so I immediately picked this up. I'm too impatient to wait for scans so I bought all of the volumes on amazon.jp so I cam finish it. I have no issue with step-sibling romances but for people who don't like it, stay away haha.
It looks like their feelings are mutual...
I read Rockin☆Heaven when I was in High School and re-reading it now I feel so nostalgic lmao. I remember how I cried during some of the major parts of the story (won't mention cus spoilers). It's a pretty good manga that gives the feel of classic shoujo. I wish more people read and appreciated...
