Nostalgia ~Back then, At That Place~
Kotegawa Yui is going to look at cats on the pet store as usual when she finds Rito on the way, they encounter the skunk of youth who broke free from Run's house. Rito tries to grab it but scares it and him and Yui end up turning young again. Eventually all of Rito's friends are turned into kids. Rito eventually was able to catch the skunk from a high wall where he almost fell but was saved by Yami. The skunk was then put into Nana's Phone where it won't disturb anymore. Back in school Yui asks Rito if he used to play around a temple she walked by and he confirmed, she then remembered he was the kid who saved a kitten that was stuck in a tree when she was young.

The Changing Heart ~Honest Feelings~
Nana enters Rito's room wanting to talk to him, she asks him if he likes big breast girls. He blushes and starts imagining big breasts, Nana seems upset but Rito replies to her saying it's not the breast size that matters and Nana even not having big breasts has her own unique appeal. Nana removes her shirt and gets on top of Rito asking him if he sees her as a woman. Rito desperately tries to get away but grabs her breast, she doesn't slap him and leans to kiss him. Momo burts out of the closet to stop them. Momo and Nana had switched minds with one of Lala's inventions and Momo was the one in Nana's body. They walk away with Nana (now in her body) blushing and thinking about what she heard Rito say.

Flower ~Budding Feelings?~
Rito finds Celine playing with some flowers he's never seen. He smells a pot that has purple flowers and then walks away. Momo finds Celine and explained how those were her flowers and no one should smell them because they can have side effects, Celine told Momo Rito had smelled the purple flowers and she was really worried since those flowers change one's personality. Rito demands Lala to give him her see through glasses and asks her to pose for him. Excited, Rito starts asking for more breasts and runs to school where he looks at each and every girl and even looks closely at Yui's privates. Momo finds Rito and heals him before anything worse happened. Rito Falls unconsious on the floor from all the things he saw.
