After the preview ends Rio go with Christina and Flora who lost her consciousness to a rocky area, and there he took the stone house(Christina saw how the house appeared).
BTW while he was carrying Christina and Flora, Christina wonders how much she smells since she remembers what Dullan said, and that was really cute.
Rio takes her to a clothing room for her to choose clothes for both her and Flora. After she chooses, she awakes Flora, they explain the situation to her and Rio says that they should there for a few days to see if Flora has fever again, after that he will send them to Rodania. Christina asks if he really will send them to Rodania and Rio asks if there is a problem if they return to Rodania, but Christina says that since he's Rio he probably doesn't think that Beltram is a good kingdom or that he doesn't have a good impression of her since she says that she did terrible things to him.
Rio asks what terrible things she did to him and asks if it's about when she slapped him, Christina turned red since she remebered that and Flora asked if she really did that and she replies that yes.
Rio says that he doesn't care about that but Christina says that it's not only that, she talks about when she pretended not to see when people where pestering him or the mayor problem with the outdoor practice, no one saw anything but they blamed Rio and even if she knew that Rio didn't do it, she didn't tried to protect him. Tio told here that if she didn't saw anything it's not good to make falsehoods. Then she asks that it wasn't him right? To what he replies that there is no way to proof that it wasn't him but he says that he wasn't and Christina and Flora said that they believe him and then both starts to thank for everything he has done for them.
I don't want to do a big summary so i'm going to summarize everything a bit more.
Christina and Flora tells him that they will not reveal his past to anyone though they asks later if Seria knows that Haruto's Rio.
They go to the bathroom and Rio explains them how the bathroom works in his house, Flora asks if that it's a bath where you can soak, she says that she have heard of that from Hiroaki and that he has one in his room, i don't remember if it was Christina or Rio who asks but one of them asks her if she has bathed in it and Flora says that no, it's the bath is on a man's room after all, and then Rio is thinking that this bath is on his house.
He says to Flora that is better not to use it today for her since she could get fever again and Christina says that in that case she will not get in today either. Rio goes for towels and Christina and Flora start to talk about the past, about how Christina met Rio and that she said cruel things to him like that he was dirty and that he stunk. They both starts to wonder if they stink but even if they tried smell therselves they couldn't know if they stunk so they started to smell each other and to their surprises Rio arrived.
The while they are in the bathroom Flora tells Christina to enter to the bath where you can soak in and tell her Christina's opinion. She enters and she really likes it. Time passes and then she feels weird, Flora goes to call Rio(you can see an illustration of her with towers) and Rio explains what happened to her, she basically feels dizzy.
The next chapter starts with Rio doing his morning training. Christina and Flora are also awake and saw him doing, they talk with him and Christina says that she remembers seeing him training after school and also seeing him at the library studying. Flora says that she really looked for Rio curious and Christina who turned red said that she was with her too. And for your curiosity, there is a SS with the volume 1 where Christina, Flora and Roana are seeing Rio training from the library.
After eat the breakfast the serious conversation starts, with Rio asking what will happen with the Restoration now that they have been disappeared for 2 days. Christina tells him that there will be nobles that will separate from Restoration and in the worst case the organization could even be divided. Christina and Flora are the shrines for the organization and now that they lost them there aren't too much nobles that would fight. Rio says that Hiroaki should be another shrine but Christina says that Hiroaki can become one but he should be engaged with Flora or Christina. Then Christina asks Rio if he could send them to Galturk instead of Rodania because now that they are not in Restoration Huguenot will try to make Hiroaki a shrine engaging him with one of François's daughters since it seems that the grand-aunt of Christina and Flora was engaged with the previous king of Galark kingdom.
But then there is a problem, if Hiroaki gets engaged with one of François's daughters and then they found out that Christina and Flora are alive, what will happen? Break an engagement is not that easy and people will start wondering why the hero is engaged with a princess of another kingdom instead of his. And since the time is a problem too, they wonder how much time they have until Huguenot starts the negotation with Galark, Rio says that he can take them there in one week Christina thinks that they have 10 days for reasons like that they first will try to search for them, etc. and says that she has a plan first, she says to go to an ally country first since then they can communicate with a magic item. She says to go to Rubia Kingdom.
After that conversation ends Christina says that she has a many things to thank and a many things that she wants to apology to him and she wanna ask him some questions. One, what happened in the outdoor practice. But before he tolds her that he had to first explain what is the seireijutsu(spiritual art). He explained them how the spiritual art works creating a water cat and why people doesn't use it, etc.
After the explanation he tolds them that he felf of the cliff safely and then returned but they were saying that Rio was the culprit bla bla bla, Christina and Flora apologies again and then Christina asked to Rio who was the one that made Flora fell and asks him if he knows, Rio replies that he knows but there's no proof that that's the truth, but Christina tells him again that she believes him and then Rio told her what really happened. Christina apologies again, he says that he's not mad because he had to left with false charges, he was to left the country after all... But Christina says that if he didn't have falses charges he shouldn't have to use an allies but then Rio says that that's true but now that he is using an allies he doesn't have to be involved with the people that put him the crimes but Christina insist that he should be angry and hate them(including her), etc. Rio says that it's not like he doesn't feel anything towards them but he has been hating someone for his entire live and it's not like he hates them enough to try to revenge agains them although he says that there is one thing that he will definitely don't forgive. Christina asks if something else happened but Rio says that this is for another person so he can't say anything right now, Christina asks if that person is Seria but he denied it saying that is another person(Latifa) and that he will tell both of them if the opportunity comes.
They return to the main subject with Rio saying that she doesn't have to feel responsible for what happened to him but she says that she can't, even if he doesn't hate her she says that she did horrible things to him, and Flora says that she also caused problems to him. Rio really doesn't know what they are talking about except for when Christina slapped him. Christina turned her face red again saying that the slap is also one of the things. Rio says that probably that moment was his fault since he touched him with his dirty hands, Christina then cried that his hands wasn't dirty and that the dirty one was her saying that Rio was pure.
There is a lot of cute scenes more but i'm already tired. so there is one more thing that I want to say.
Before leaving, Rio decides to how to carry Christina and Flora, and then they decide to do it like he did when he brought Christina and Flora to the Rocky area, carrying Flora like a princess and Christina on his back. Then Christina notices that her breast are touching Rio's back and then she commented that thanks god it's not Flora who is in the back since her breast are bigger.
That's the best scene of this volume change my mind.
