A Father’s Blind Spots

A Father’s Blind Spots
Love mixed with failure
Kimura cares deeply for Wataru, yet his drinking and impatience repeatedly shape their days. Wataru sees him take a hidden sip and learns to recognize the excuses that accompany it.
The relationship is affectionate but unequal: the child is attentive to his father’s condition, while Kimura often understands his own behavior only afterward. That history makes his later remorse especially painful.
A Coma and a Promise

A Coma and a Promise
The cost of absence
After Wataru falls, Kimura spends weeks at the hospital, tending to him and speaking beside his unresponsive bed. He has stopped drinking, but cannot make his son wake or answer.
When Kimura finally leaves for the train, he asks other parents to watch over Wataru. He believes the revenge trip will be brief, not realizing the Prince will turn the hospital into a source of leverage.
The Grandparents’ Assurance

The Grandparents’ Assurance
Protection beyond the train
Shigeru and Akiko respond to the threat against their family by contacting an old associate and arranging protection for Wataru. The message delivered through the carriage display confirms that the child is safe.
The news changes Kimura’s emotional position even though he remains in danger. His parents’ intervention makes his son’s survival a family effort rather than the outcome of the Prince’s rules.
