If she poses a threat to his life again

"The sudden change is a little strange." Rie asks Kiyohira with worry, "Did he not tell you why? His young friend lost her mother and grandfather. We should see the girl."

Yuta has been playing games all day. Though he has been trying to act as if there's nothing wrong, even a stranger could tell that the little boy is going through a whirlwind of emotions that are not suitable for his young body. 

Right now, he's practising calligraphy in his room.

Kiyohira sighs. Everyone has their own way to deal with complicated emotions. He wonders if he should send Yuta to live with Takeshi for a while. If he's away from Mira, he might be able to forget. 

"Why did he suddenly change his mind about bringing her to our family? Did they have a fight?" Rie narrows her eyes. 

"She remembers her past life." Kiyohira closes the book.
