"Itadakimasu." The two said before digging in.
"Ruri-chan, do you know how to eat fish or do you want me to help you pick out the bones." 
"I am a skilled eater~."
"Oh, you really are." He was thinking what a skilled little eater she was. His own son on the other hand, he had to help him pick out the bones. He smiled fondly because he wondered how his son was doing. Was he eating well? Playing well? Living well? He wondered if his son missed him? Ah...but after he refused to come round last time, maybe his son now hate him like his ex-wife.
"Papi's miso soup is warm." 
"Huh?" He snapped out of his own thoughts.
"Nee-chan and Papi's miso soup is warm."
Tamaru drank the miso soup he made. It was nice and hot after blowing it a few times to drink. "Do you like miso soup, Ruri-chan?" 
"I do!"
"And it's pretty hot. Be careful not to scald yourself." 
"Okay~."
Wait. "Ruri-chan, the soup is hot so what do you mean it's 'warm'?"
"Hm? Hmm~." She gave it some thoughts because she's not too sure how to put it in her own words. "I don't know Nee-chan's miso soup and Papi's miso soup makes me feel nice and warm. The ones in school tastes good but it doesn't make me feel warm." 
"They're serving it cold?" 
"No. Not that. Just..." she touched her own heart, "It's warm here. Miso soup made by Nee-chan and Papi."
Ah. Tamaru understood now. "I see." He's very happy. He's so happy he couldn't stop smiling to himself; the warmth this little girl was talking about had nothing to do with the temperature of the soup. She's talking about the taste of 'family' through the soup; when you start cooking not just for yourself but for people you care about, the taste tend to make you feel warm in the heart.
"Grow up to be a good kid, Ruri-chan." 
"Hm! I'll be a good kid, I'll get a good job, make money, take care of Nee-chan, and then I'll unify Japan." She was flicking through the channels one time and she watched near the end of a historical drama. She didn't understand what the warlord meant by unifying Japan but she thought it was cool. 
"Oh! You've watched that historical drama about Oda Nobunaga? Aren't you a bit too young for it?"
"Ehehee~." Ruri then remembered something, "Papi, why don't we invite Kotarou?" 
"I want to, but he's not in his room. I wonder where they went? That guy always going off somewhere with my dear little Kotarou-kyun...! I'll never forgive him!"

So what job did Rio take up?
Rio was doing her makeup because her job was working inside a hostess club called 'Club Dream', the same hostess club Mizuki worked at. Rio was covering for an employee because the poor girl was ill. The manager need enough girls to fill in and when he was given Rio's card, he called her, negotiated a price with her, and then he got her working.
"I have to take care of Ruri so I will not drink alcohol." She's having her makeup done by the bartender of Club Dream.
"Oh look at you, Ri-chan~! You're so beautiful! So pretty! Men are so happy to see you and talk to you!" The bartender wiggled his butt in glee because he's so proud of his makeup applying skills. The before and after was phenomenal! She looked beautiful before but she looked even more beautiful after makeup! He's so proud! He's crying like a father about to walk his own daughter down the aisle!
