Follows the characters Sena Shougo and Sagara Rei's story from Love Stage.
NO SPOILER - You can really see that these are just bonus chapters. If you haven't read the main story, then "Back Stage" is definitely not what you should be reading. If you do that, you won't understand the context, believe me. Anyway, I give 5/10 because some things could definitely have been better. Much better...but this story is my heart's matter and I always laugh a lot, so from that perspective, manga didn't disappoint me. I only recommend this to true "Love Stage" fans.
