(Holy Graal, thank you, I can’t-)
Like always, my sweet Asinelly, I can’t draw, but you push me to do so because you all are such big cinnamorolls. Therefore, I’ll draw a family moment, in which Itsuki and Toshiō are enjoying their walk (Itsuki will stay a child inside forever XD), while Makoto isn’t having fun, because Mirai is starting making a fuss about how much she wants Daddy to put her on his shoulders like Mommy is doing. If Makoto doesn’t want to do something, he won’t; there’s nothing to do.
Mirai loves wearing ribbons just like Itsuki, so she would be happy, if you gave her a ribbon as a present. Itsuki would scold Makoto a lot, since he would choose to buy the worst ribbons she has ever seen.
“I will never understand girly stuff. I’ll buy her a stuffed toy, instead!”
And yes! Toshiō is as chubby as his father, even though Mirai would be like that too. He would be a little puffy Jen XD, but, ehy, don’t try pinching his cheeks like some people do: he could bite your hand, I’m not joking. Remember this kid is Makoto’s son and has got Ruki has grandmother, so be careful ahhahah.
As far as concerns Yang, I agree with you a lot. Even though he would struggle to figure that, because he isn’t used to being loved or loving someone, he would slowly realize that, I’m sure. Itsuki and Makoto would be so concerned about his life, because, like I said before, his heart would go through a lot. Therefore, they would also commit themselves to make him understand they are his family and they’ll also be by his side when he needs to cheer up or feels lonely.
He would struggle to understand why those kids love him so much, but after a while he wouldn’t mind or worry about it at all. He would stop being concerned about how to love or how to be loved. The answer would appear before his eyes: there are no questions or real answers about love: you have to love and never stop doing that.
After all, how would he be able not to smile at the sight of the kids playing baseball with him or of Toshio playing with his planes and rescuing cats just like he used to do when he was younger (Makoto will curse him, though).
PSA: He would also laugh a lot at the sound of the kids calling him “Kichō”, which means first pilot in command. Ahaha, he would feel a bit proud of himself.
