"Are you two ready for your first day of school?" Kaito asks.
"Yeah dad we are." Rin and Len say at the same time.
"Mom is probably proud of us right now." Rin says.
"Who, Miku?" Kaito asks.
"Not Miku my real mom." Rin replies.
"Oh yeah. I forgot you don't call Miku mom, but you call her by her real name. But Len calls her mom." Kaito suggests.
"It just feels weird. She's not my real mom so why should I call her mom when my real one is dead? Lenny-Kun is a mommy's boy so of course he'll call Miku mom." Rin says.
"I'm not a mommy's boy!" Len shouts from upstairs.
"You are Len. Whenever I punch you can't withstand the impact." Rin says sarcastically.
"That's because you're like a bear." Len jokes.
"Come on you two don't fight. Rin seems to take after her mother." Kaito says reassuringly.
Rin and Len get ready for their first day of middle school. They have the same classes as each other where they meet new students. Len has changed a lot but High school is going to be tough for him because he was a genius. They are in the same classes with Oliver their childhood friend since kindergarten. They are enjoying their first day of school. Their middle school years was easy on Kaito becuase he didn't have to worry about them since they are passing their classes.
Kaito is at home taking care of Mikuo he is learning how to talk and walk. He has the same pitch as Len had accept a little higher than him when he was young. Rin hit puberty in 7th grade so finding new clothes for her was hard because of her body type. She was always skinny but she got really tall. She was as least 5ft 7 inches by 8th grade. But she'll continue to grow until Len starts; then she'll be at the end of her growth spurt. Rin got honor roll throughout her middle school years but Len got Principle's honor roll. Mikuo is growing up and will go to preschool eventually. There were times when Rin started acting withdrawn from the family where she would never eat with them at the table especially with Len. So Kaito allowed her to eat in her room if it was where she felt comfortable. Her only schedule was do homework, eat, and sleep. Len on the other hand would hang out with Oliver with Rin on the weekends where they went to the mall together.
Author's notes: Sorry for the short chapter its supposed to compliment step child and life after Mikuo was born. This may happen for a few chapters in this story.
