Is Onodera's Jing Ping and Nana a formal match?

These two are not official competitions.

In the work "Pet Girl in Sakura Village", there is a deep emotional foundation between Onodera Jinggu and Xintian Meihe, and there are also many interactions and developments between them. Nana is a later figure, and there is no clear love clue or special relationship between her and Onodera Jinggu. Therefore, judging from the plot, Onodera Jinggu and Nanna are not a formal match.
