I think that we should leave some of them alone. Nana's relationship with Rito is important since Momo included Nana in the Harem Plan and Nana's character plays a bigger role in TLR:D. So Nana should not be removed. The others I think we can safely remove or cut short (ex. Peke, who rarely speaks to Rito)

As for why Mikan's entry in Momo's page was removed, I don't know why someone would delete that since Mikan's rivalry with Momo is considered important. I'll see if I can fix it.
