Same concept here really. Same sad broken main character after the loss of a loved one. The 2nd girl tries to bring him to her side but ends up getting hurt in the process, although in RK "reflections", the main heroine completely fails, where the main girl in "rumbling hearts" gets a happy ending in the end.
You should watch this if you enjoy the pain and realism that people go through in love triangles, and how people deal with the loss of a loved one.
These two anime are similar in an abstract way.
