It sounds like you might be referring to "To LOVE-Ru" (often stylized as To Love-Ru), a popular Japanese manga and anime series. The "ova" part likely refers to the OVA (Original Video Animation) episodes released for the series.

Here’s a quick breakdown:

• To LOVE-Ru is a romantic comedy / harem manga by Saki Hasemi and Kentaro Yabuki. It follows Rito Yuki, a shy high school student whose life gets chaotic when an alien princess named Lala accidentally gets engaged to him.
• The series has several anime adaptations, including To LOVE-Ru (2008), Motto To LOVE-Ru (2010), and To LOVE-Ru Darkness (2012–2017).
• OVAs were released alongside certain manga volumes. These are typically side stories, often more ecchi-focused than the TV series, and sometimes adapt bonus chapters.

If you're asking about where to watch the OVAs or which OVAs exist, let me know and I can help list them. If you meant something else by "to love ova," feel free to clarify!
