"A mother should always be there for her family, instead of being busy working and working. And when Kyo gets happiness when fighting, why does Mama protest? Where have you been all this time when Kyo and Ken feel lonely, Ma?"
"Indeed Mama never existed and cared about Ken and Kyo! Does Mama know how we have felt all this time? We feel lonely, Ma!"
"Ken has Mama but it feels like Ken doesn't have one. Mama has caused Kyo to run away from home! If it's like this, it's better if we don't have a mom!"
Ken screamed at his mother when he found out why Kyo ran away from home.
Mrs. Kenkyo said that she felt guilty for making Kyosuke run away from home.
This made Kensuke, who had been looking for Kyosuke for several days, feel frustrated to the point of blaming his mother because Kyosuke had not come home.
Kensuke had never fought his mother before. But, because Kensuke was desperate to find Kyosuke, in the end Kensuke vented his anger on his mother.
