Mio couldn't wait to talk to Nagi, she also wanted to know Kaito's reaction, so she pushed him to talk in the classroom although he was reluctant to talk because it was embarrassing for him to talk in the room where he didn't want anyone to know how far that Nagi and Kaito had gone. Mio was curious if Nagi had taken her advice and what had happened,she is also curious about Nagi's first time, she said somethings to Kaito that normally you wouldn't think a girl would say. Mio still has an unhealthy attachment to Kaito, for a half-sister! Nagi isn't worried about her education because she already has good job opportunities available with her parent's company, she wants to stay near Kaito. Kaito feels he is not really smart enough to be around Nagi as more than a servant or house husband. Kaito is smarter than he thinks, he is quick to learn if someone takes the time to work with him, he's dependable, will stick to what he's doing, his only disadvantage is the time he lived with his mother, and with time and the help of others he can overcome that, he has time to bring up his grades and go to almost any college he wants to, he just has to ask for tutoring or study with someone. sorry for being so long. thanks for the story it's enjoyable and very interesting.
