She looks up to Yuzu and desires to become more like her, even dying her hair blonde like Yuzu's. She later dyes her hair back to the natural color as she didn't want to cause more problems to Yuzu. She is grateful to Yuzu and the others for having accepted her even after all of the trouble she had unintentionally caused them.
Like with Yuzu, Nene looks up to Harumi. She seems to have a fantasy of Yuzu and Harumi being lovers.
Nene frist met Matsuri outside a cafe Yuzu and Harumi were at, where she was fantasizing about her HaruYuzu. Matsuri teased her by saying she is Harumi's girlfriend and that Harumi doesn't romantic interest in Yuzu. But she refused to believe it, they met again at the pool and at the summer festival than later outside of cafe on a rainy day. But she didn't remember Matsuri until she remember her as the self-proclaimed girlfriend of Harumi.
