A good and sometimes funny romance disguised as a harem. Shino's alter-ego's can't be considered full people in their own right since they ultimately depend on their relationship with Shino to keep living. As such, the manga is more a romance with a very expressive Shino rather than a harem. Unexpected, but nice as a romance. There was romantic development and intrigue spurred on by Shino's alter-ego's, so this didn't drag on as much other romance does. The slapstick humour was ok, better than Fujimara-kun Mates since not all of it was based at Souta's expense.
The biggest problems were generally a lack of drama and an axed ending. It is almost disgusting to see this axed after just 37 chapters despite being objectively much better than Fujimara-kun Mates. This manga deserved more chapters than it was given, woe be the Japanese audience. Still, the series was fine overall.
6/10.
Agree on the 6/10. The ending's not horrible, but another chapter or two to show how things work out for them would be nice.
I disagree on the comparison to Fujimara-kun Mates, though. What made Fujimara-kun Mates so unique was that the entire world was absurd and Fujimara was basically the only normal person in it. He couldn't help being swept away by the insanity because it was literally everywhere. Every character was unique and had something interesting going on with them.
With this manga, almost all of the weirdness is confined to Shino. Shino isn't very interesting on her own - it's her clones that actually give her character. Considering they're the most interesting part of the story, they don't really do all that much outside of cheering Shino on. There were some interesting side characters, but they never had a chance to shine.
Compared to Fujimara-kun Mates, this manga seems like it just consistently misses the mark. Good ideas, but poor execution. The romance is better, sure, but if romance is what you want then oddball comedy manga isn't the right place to look anyway.
