Yep, there's a lot of love in Inuyasha; Naraku loves Kikyou who loves Inuyasha who loves Kikyou and Kagome (who loves Inuyasha back), but Houjou and Kouga also love Kagome, and Ayame loves Kouga. Miroku loves Sango and every attractive woman he meets, and Sango loves Miroku. Shippou loves the little orphan girl with the fake Shikon fragment.

I'm forgetting some, I know. It's possible that Inuyasha has feelings for Shippou or Kaede, even. The beautiful Sesshoumaru loves no one. XP

Full Moon wo Sagae has a cute and funny love story. I think it's best in manga form, though.
