"To love ova" is likely a typo or mishearing of "To Love-Ru" (pronounced "To Love-Ru," sometimes written as To LOVEる), a popular Japanese manga and anime series.

Here's a quick breakdown of what it is and the "OVA" connection:

To Love-Ru (Series Overview)

• Genre: Romantic comedy, harem, sci-fi, ecchi (mature content).
• Creator: Saki Hasemi (story) and Kentaro Yabuki (art).
• Premise: High school student Rito Yuki accidentally confesses to the alien princess Lala Satalin Deviluke, who then decides to marry him to avoid an arranged political marriage. Chaos ensues as more alien girls enter his life.

The OVA Connection The series has several OVAs (Original Video Animations) — episodes released directly to home video rather than TV. These include:

• To Love-Ru OVA (2009–2010): 6 episodes bundled with manga volumes.
• To Love-Ru Darkness OVA (2012–2015): 8 episodes tied to the sequel manga To Love-Ru Darkness.

If you meant something else (e.g., a specific OVA title, or a different phrase like "to love over"), feel free to clarify!
