Just finished this series, I feel empty right now. Should I read the manga?
The manga is great and the art is amazing, especially the eyes and hair. The scanlation group is kinda dead though.
You should, and you should read the Oomuro-ke manga too. You don't see anything of Nadeshiko's harem in the show really. Plus Hanako has a pet tsundere loli.
There's sadly not that much of it, given the chapter lengths, but it's good.
